                               PROSPECTUS SUMMARY

    THE  FOLLOWING SUMMARY  IS QUALIFIED  IN ITS  ENTIRETY BY  THE MORE DETAILED
INFORMATION AND  CONSOLIDATED FINANCIAL  STATEMENTS APPEARING  ELSEWHERE IN,  OR
INCORPORATED BY REFERENCE INTO, THIS PROSPECTUS.

                                  THE COMPANY

    VLSI  is a  leader in  the design,  manufacture and  sale of  highly complex
application specific integrated circuits ("ASICs") -- custom designed chips  for
an  individual customer -- and  application specific standard products ("ASSPs")
- -- semi-custom chips designed  for a particular market  application that may  be
used  by several different customers. The Company targets high volume markets in
which it has built significant expertise and can use its library of  proprietary
cells  and highly  integrated building blocks  to assist  customers in designing
products and bringing them to market rapidly. VLSI's target markets include  the
computing,   communications  and   consumer  and   entertainment  markets.  VLSI
emphasizes  high  performance  applications  where  its  products  are  critical
elements  of complex electronic systems. VLSI  targets key OEM customers who are
leaders in their  respective industries. The  Company's major customers  include
Compaq, Apple, Ericsson, Hewlett-Packard, Tellabs, Alcatel and Silicon Graphics.

    VLSI  produces a  significant portion  of its  wafers (approximately  73% in
1994) at its own  facilities and augments  internal manufacturing capacity  with
the  foundry services of third-party  wafer subcontractors. The Company believes
that this  strategy  improves  quality,  cost-effectiveness,  responsiveness  to
customers,  access  to  capacity,  ability  to  implement  leading  edge process
technology and time to market, as compared to semiconductor companies that  lack
fabrication facilities. The semiconductor industry is, however, currently facing
capacity  constraints in wafer manufacturing and the availability of third-party
wafer foundries has diminished significantly. Due to this manufacturing capacity
shortage, as  well as  increased  customer demand,  the  Company is  seeking  to
accelerate   the  expansion   and  upgrading   of  its   internal  and  external
manufacturing capacity.

    Through its subsidiary,  COMPASS Design Automation,  Inc. ("COMPASS"),  VLSI
offers  an  integrated suite  of electronic  design automation  ("EDA") software
tools, foundry-flexible libraries and  support services for  use by systems  and
circuit designers at other semiconductor and systems companies as well as at the
Company in creating complex integrated circuits.

    The  Company's principal executive offices are  located at 1109 McKay Drive,
San Jose,  California  95131,  and  the  Company's  telephone  number  is  (408)
434-3100.

                                  RISK FACTORS

    IN  ADDITION TO THE OTHER INFORMATION PROVIDED IN THIS PROSPECTUS AND IN THE
DOCUMENTS INCORPORATED  BY REFERENCE  HEREIN, THE  FOLLOWING FACTORS  SHOULD  BE
CAREFULLY   CONSIDERED  IN  EVALUATING  THE  COMPANY  AND  ITS  BUSINESS  BEFORE
PURCHASING THE COMMON STOCK OFFERED BY THIS PROSPECTUS.

    FLUCTUATIONS IN OPERATING  RESULTS.   The Company believes  that its  future
operating  results will  be subject  to quarterly  variations based  upon a wide
variety of  factors, including  the cyclical  nature of  both the  semiconductor
industry  and the  markets addressed by  the Company's  products, price erosion,
competitive factors, fluctuations  in manufacturing  yields, the  timing of  new
product  introductions, changes in  product mix, the  availability and extent of
utilization  of  manufacturing   capacity,  product  obsolescence,   scheduling,
rescheduling  and  cancellation  of large  orders,  the ability  to  develop and
implement new  technologies,  changes  in effective  tax  rates  and  litigation
expenses.  The Company's  COMPASS subsidiary,  like other  companies in  the EDA
business, is particularly subject to significant fluctuations in revenues due to
limited backlog and its reliance on large orders placed late in the quarter. The
Company  increases  its   level  of   operating  expenses   and  investment   in
manufacturing  capacity in  anticipation of  future growth  in revenues.  To the
extent this revenue growth does not materialize, the Company's operating results
would be adversely affected. In circumstances where the Company is operating  at
less  than  full  capacity or  has  targeted  a market  segment  as  a long-term
strategic focus, the Company may choose, in the face of severe pricing pressure,
to manufacture products at low or no profitability. The Company's second quarter
financial results  will be  adversely  affected by  a  $19.4 million  charge  to
earnings  relating to a May  1995 verdict against VLSI  in a patent infringement
lawsuit. See
"-- TI Litigation; Intellectual Property Matters" and "Recent Developments -- TI
Litigation."

    MANUFACTURING CAPACITY LIMITATIONS.  The Company's manufacturing  facilities
are  operating at capacity.  As a result,  VLSI's growth is  constrained and the
Company has experienced difficulty in  meeting some delivery dates requested  by
customers.  Prolonged inability of  VLSI to deliver products  in a timely manner
could result in the loss of customers and materially adversely affect results of
operations.   In   addition,   the   Company   is   experiencing   manufacturing
inefficiencies associated with the operation of its facilities at capacity while
simultaneously working to expand or upgrade that capacity. Significant lead time
is  required to acquire  and install additional  wafer fabrication equipment. To
the extent that the Company is unable to procure and install such equipment in a
timely manner, the increase in wafer production capacity at its facilities would
be delayed.

    In addition, available third-party wafer fabrication, assembly, testing  and
packaging  capacity has become very limited in recent months. The Company relied
on two outside  suppliers for approximately  27% of its  1994 wafer  production.
Although the Company has ongoing relationships with these suppliers, the Company
has  only one contract for guaranteed  capacity. The other supplier has notified
the Company that it  will sequentially reduce its  allocation of wafers to  VLSI
from  the  third quarter  of 1995  through the  second quarter  of 1996  and has
indicated that it does  not intend to supply  wafers to the Company  thereafter.
There  can  be no  assurance  that such  supplier  will not  further  reduce its
allocation to VLSI. The Company will be required to find alternative sources  of
wafer  supply to replace  the capacity previously provided  by such supplier. If
the Company is  unable to  replace such wafer  supplier, its  sales of  products
would be diminished, which could have a material adverse impact on the Company's
operations.  In addition, the  Company relies on three  suppliers for almost all
assembly operations  and  a  significant  portion of  test  operations  and  any
reduction  in  allocation  from  these  suppliers  would  adversely  affect  the
Company's operations.

    MANUFACTURING RISKS.  The fabrication of integrated circuits is an extremely
complex and  precise  process  consisting  of hundreds  of  separate  steps  and
requiring   production  in  a  highly   controlled,  clean  environment.  Minute
impurities, errors in any step of the fabrication process, defects in the  masks
used  to print  circuits on  a wafer  or other  factors can  cause a substantial
percentage of  wafers  to be  rejected  or numerous  die  on each  wafer  to  be
nonfunctional.  The  Company  may experience  problems  in  achieving acceptable
yields in  the  manufacture  of  wafers, particularly  in  connection  with  any
expansion  of its capacity  or change in  its processing steps.  For example, in
late 1992, the Company switched processes

                                       5
<PAGE>
at one step in the manufacturing line, which caused certain VLSI chips to  fail.
The Company's replacement of these chips at no charge to the customers adversely
affected results of operations in the first quarter of 1993.

    In  addition  to  manufacturing  in  its  own  facilities,  VLSI  has  wafer
manufacturing arrangements with two integrated circuit manufacturing  companies.
These  wafer subcontractors are  themselves subject to  all of the manufacturing
risks that  are applicable  to VLSI's  own wafer  manufacturing operations.  The
Company  also subcontracts virtually all of its integrated circuit packaging and
a significant portion of  its final testing to  third parties, principally  ANAM
Industrial  Company in Korea, ASE  Corporation in Taiwan, Advanced Semiconductor
Assembly Technology in Hong Kong and Mitsui Incorporated in Japan. In  addition,
the  Company's  foreign subcontract  manufacturing  arrangements are  subject to
risks such as changes in  government policies, transportation delays,  increased
tariffs,  fluctuations in foreign  exchange rates, and  export and tax controls.
Any problems experienced in obtaining  acceptable wafers from third party  wafer
subcontractors on a timely basis to augment the Company's internal manufacturing
capacity  or in the  integrated circuit packaging,  assembly and test operations
performed by subcontractors could delay shipments of the Company's products  and
materially adversely affect the Company's results of operations.

    The  Company's success  is also  dependent upon  its ability  to develop and
implement new  manufacturing  process  technologies.  Semiconductor  design  and
process methodologies are subject to rapid technological change, requiring large
expenditures  for research and  development. Most of  the Company's products are
currently manufactured  using sub-micron  CMOS processes.  The Company  believes
that  the transition to smaller geometry  process technologies will be important
to remaining  competitive.  The Company  is  in  the process  of  expanding  and
upgrading  its  manufacturing  facility  in  San  Jose,  California  to  convert
production to a 6-inch CMOS wafer  process. The Company's San Antonio  facility,
which  is currently  using both  0.6-micron and  0.8-micron processes,  is being
converted  to  100%  0.5-micron   CMOS  process  capability.  These   conversion
activities could result in a disruption to the facilities' manufacturing cycles,
thereby  lowering the output of the facilities as well as wafer yields. Any lack
of success of the Company's facilities conversion efforts would have a  material
adverse  effect on future operating results and, in particular, delay of planned
increased production of 6-inch CMOS wafers  at the San Jose facility,  currently
scheduled  for  the  third quarter  of  1995, could  adversely  affect near-term
results.

    The Company is party  to a joint development  agreement with Hitachi,  which
expires  in 1997. Under such agreement, the Company and Hitachi work together to
develop  advanced  sub-micron  processes  for  the  manufacture  of   integrated
circuits.  In addition,  the Company is  dependent on Hitachi  for assistance in
developing  other  state-of-the-art  manufacturing  processes.  Any  failure  or
disruption  of the Company's joint development  activities could have a material
adverse  effect  upon  the  Company's  ability  to  implement   state-of-the-art
manufacturing processes.

    The  Company's San Jose  facility, which accounted  for approximately 42% of
its total internal  production in  the first quarter  of 1995,  is located  near
major  earthquake faults and in an area  that has in the recent past experienced
an extended drought. Even  though the Company utilizes  both of its  fabrication
plants  and two subcontractors to manufacture its  wafers and has the ability to
shift manufacturing  from  one  plant  to another  for  many  of  its  products,
disruption  of operations at either of the Company's production facilities or at
those of its subcontractors  for any reason, such  as fire or earthquake,  would
cause  delays in shipments until  the Company could shift  the products from the
affected facility or subcontractor to another facility.

    FUTURE CAPITAL NEEDS.  Semiconductor companies such as VLSI have substantial
ongoing capital  requirements  to  obtain  internal  or  external  manufacturing
capacity.  In order  to remain  competitive, the  Company must  continue to make
significant investments in  capital equipment  and expansion  of facilities,  as
well   as  in  research  and  development.  Development  and  implementation  of
sub-micron manufacturing processes is particularly capital intensive,  requiring
significant investments in new state-of-the-art equipment. The Company currently
anticipates  that its capital  expenditures for 1995  will be approximately $200
million. The Company believes that the net proceeds from the sale of the  Common
Stock in

                                       6
<PAGE>
this  offering, together with existing cash balances, cash flow from operations,
available equipment financing and proceeds  from the expected exercise by  Intel
of  its warrant for an aggregate  exercise price of approximately $31.3 million,
will be  sufficient to  meet the  Company's liquidity  and capital  requirements
through  1996. However, the Company is currently exploring methods of increasing
both its internal and external manufacturing capacity. As a result, the  Company
may  be required or choose  to seek additional equity  or debt financing to fund
further expansion of its internal or external wafer fabrication capacity or  for
other  purposes. The  timing and amount  of such capital  requirements cannot be
precisely determined and will  depend on a number  of factors, including  demand
for  the  Company's products,  product  mix, changes  in  semiconductor industry
conditions and  competitive  factors.  There  can  be  no  assurance  that  such
additional  financing will be available when needed or, if available, will be on
satisfactory terms. The failure to  obtain financing would hinder the  Company's
ability to make continued investments in capital equipment and facilities, which
could materially adversely affect the Company's results of operations.

    DEPENDENCE  ON PERSONAL COMPUTER INDUSTRY.  The Company estimates that total
sales to the personal computer market during 1994 represented approximately  47%
of  the Company's net revenues. With five  of the Company's top ten customers in
1994 operating in the  personal computer industry,  a deterioration of  business
conditions  in  the personal  computer industry  would  have a  material adverse
effect on VLSI's  operations. The personal  computer market is  volatile and  is
subject  to  significant  shifts  in demand  and  severe  pricing  pressures. In
addition,  the  market   for  the   Company's  personal   computer  devices   is
characterized  by  rapid  technological  change  and  product  obsolescence. The
Company's results  in the  PC  market will  also be  dependent  in part  on  the
Company's ability to respond quickly to new microprocessor architectures adopted
by  major OEMs.  The Company's need  to anticipate  customer product transitions
also leads to  potential inventory  exposure, which could  adversely affect  the
Company's financial results.

    CYCLICAL  NATURE OF THE SEMICONDUCTOR  INDUSTRY.  The semiconductor industry
has historically been characterized by  wide fluctuations in product supply  and
demand.  From  time  to  time, the  industry  has  also  experienced significant
downturns, often in connection with, or in anticipation of, declines in  general
economic  conditions. These downturns, which in  some cases have lasted for more
than a year, have  been characterized by  diminished product demand,  production
over-capacity  and subsequent accelerated  erosion of average  sales prices. The
Company, like other semiconductor manufacturers with fabrication facilities, has
high fixed  costs  for  its  manufacturing  facilities  and  believes  that  its
operating  results were adversely  affected by an  industry-wide downturn in the
demand for semiconductors in 1990. This downturn coincided with the recession in
the U.S.  economy and  slower  growth in  various electronics  industries  using
semiconductors,  including market segments  in which the  Company was engaged at
the time.

    NEW PRODUCT RISKS.  The Company's  future success depends on its ability  to
continue  to develop and introduce new  products that compete effectively on the
basis of  price and  performance  and that  satisfy customer  requirements.  New
product  development  often  requires long-term  forecasting  of  market trends,
development and implementation of new processes and technologies and substantial
capital commitments. If the  Company is unable  to design, develop,  manufacture
and  market  new products  successfully and  in a  timely manner,  its operating
results will be materially  adversely affected. No assurance  can be given  that
the Company's product and process development efforts will be successful or that
new  products will achieve market acceptance.  For example, the Company expended
considerable financial  and technical  resources during  1993 and  part of  1994
toward  the development of its Polar product, a device intended for the handheld
computer market integrating Intel's  386SL microprocessor. Because the  handheld
market  developed more slowly than initial  expectations, the Company and Intel,
its partner in  the Polar  development effort,  canceled the  Polar project  and
terminated the amended July 8, 1992 Technology Agreement between the companies.

    COMPETITION.  The semiconductor industry in general and the markets in which
the  Company competes in  particular are intensely  competitive, exhibiting both
rapid technological change and ongoing price erosion as technologies mature. The
Company   competes   with   large   domestic   and   foreign   companies    that

                                       7
<PAGE>
have  substantially  greater  financial,  technical,  marketing  and  management
resources than the  Company, such  as AT&T, IBM,  Intel, LSI,  Motorola, TI  and
Toshiba.  Competition is particularly intense in  X86 core logic chip sets where
Intel, a dominant supplier of microprocessors to the PC industry, has become the
major supplier of Pentium PC chip sets, as well as motherboards, which is likely
to cause increased pricing  and margin pressure on  such chip sets.  Competition
faced  by COMPASS in the EDA market comes primarily from a few large established
vendors, such as  Cadence and Mentor  Graphics. There is  no assurance that  the
Company will be able to compete successfully in the future.

    CONCENTRATION  OF CUSTOMER BASE.   Approximately two-thirds of the Company's
net revenues for 1994 were derived from  sales to its top 20 customers, a  large
percentage  of which are in  the personal computer business.  As a result of the
concentration of the Company's customer  base, loss or cancellation of  business
from  any of these major customers,  significant changes in scheduled deliveries
to any of these customers or decreases in the prices of products sold to any  of
these  customers  could materially  adversely  affect the  Company's  results of
operations. These risks of  customer concentration are  exacerbated by the  fact
that  the Company's agreements  with its customers for  the purchase of products
are generally terminable by such customers  at any time and permit customers  to
cancel  orders previously placed for the Company's products without penalty. For
example, in the fourth quarter of 1993,  Apple, which accounted for 19% of  1993
net  revenues,  postponed and,  in  certain cases,  canceled,  approximately $20
million  of  shipments  originally  planned  for  delivery  in  1994,  adversely
affecting  VLSI's  1994 results  of operations.  Shipments to  another customer,
Compaq, accounted for 22% of net revenues in 1994 and 11% of net revenues in the
first quarter of 1995.

    TI LITIGATION; INTELLECTUAL PROPERTY MATTERS.   The Company is one of  three
defendants in a major patent infringement suit brought by Texas Instruments with
respect to patents that have now expired, which suit resulted in a May 1995 jury
verdict  against  VLSI for  damages  of $19.4  million.  The Company  intends to
contest the verdict. However,  the Company will record  a charge to earnings  of
$19.4  million in the second  quarter of 1995. Based  on the jury's finding that
the alleged infringement  was intentional, TI  may also request  that the  judge
award treble damages. In the event that treble damages are awarded, the judgment
could  result in  a material  reduction in  liquidity, as  well as  an increased
impact on the Company's reported results of operations. See "Recent Developments
- -- TI Litigation."

    The semiconductor industry is generally characterized by vigorous protection
and pursuit  of  intellectual  property  rights and  positions,  which  have  on
occasion  resulted in  protracted litigation  that utilizes  cash and management
resources, which can  have a  significant adverse effect  on operating  results.
There  can be no assurance that additional intellectual property claims will not
be made  against the  Company in  the future  or that  the Company  will not  be
prohibited  from using the technologies subject to such claims or be required to
obtain licenses and make corresponding royalty payments for past or future  use.
There  can  be  no  assurance  that  any  such  licenses  could  be  obtained on
commercially reasonable terms.

    AVAILABILITY OF RAW  MATERIALS.   Raw materials essential  to the  Company's
business  are  generally  available  from  multiple  sources.  However,  due  to
increased levels of demand, there may be an industrywide shortage of raw silicon
wafers. A  prolonged  inability  to  obtain silicon  wafers  or  any  other  raw
materials could have a material adverse impact on the Company's business.

    ENVIRONMENTAL  REGULATIONS.  The Company is subject to a variety of federal,
state and local governmental regulations related to the storage, use,  discharge
and  disposal of  toxic, volatile or  otherwise hazardous chemicals  used in its
manufacturing process.  Increasing  public attention  has  been focused  on  the
environmental  impact of  semiconductor manufacturing  operations. The Company's
San Jose, California facilities are located near residential areas, which  could
increase  the incidence of environmental complaints or investigations. There can
be no assurance that  changes in environmental regulations  will not impose  the
need  for additional capital equipment or other requirements. Any failure by the
Company to  control the  use of,  or adequately  to restrict  the discharge  of,
hazardous  substances under present or future  regulations could subject VLSI to
substantial  liability  or  could  cause  its  manufacturing  operations  to  be
suspended. Such liability or suspension of manufacturing operations could have a
material adverse effect on the Company's operating results.

                                       8
<PAGE>
    VOLATILITY  OF STOCK PRICE.  The  Company's Common Stock has experienced and
can be expected  to experience  substantial price volatility.  In addition,  the
stock  market in general has experienced  extreme price and volume fluctuations,
which have particularly affected the  market price of many technology  companies
and  which  have often  been  unrelated to  the  operating performance  of those
companies. See "Price Range of Common Stock and Dividend Policy."

    EFFECT OF POTENTIAL STOCK SALES.  Intel has the right to demand registration
of  2,677,604  shares  of  Common  Stock  issuable  upon  exercise  of  a  fully
exercisable  warrant. Such rights may be exercised by Intel at any time, subject
to the Company's ability to  delay registration for 90  days if Intel makes  the
demand  during an offering by  the Company or the  Company initiates an offering
within 30 days of Intel's demand. There can be no assurance that Intel will  not
elect  to exercise its demand right during or shortly after this offering, which
election could adversely affect the market price of the Company's Common  Stock.
In  addition, as of March 31,  1995, approximately 3,742,984 vested and unvested
shares of  the Company's  Common Stock  (the "Option  Shares") were  subject  to
employee  and director  stock options  having exercise  prices below  the market
price of the  Common Stock  shown on  the cover  page of  this Prospectus.  Many
optionees  may  choose  to exercise  their  options  and sell  the  Common Stock
acquired upon  exercise in  the  coming months  due  to the  significant  spread
between  the exercise prices and current  market prices. Shares of the Company's
Common Stock are  currently trading  in excess of  the conversion  price of  the
Company's  convertible subordinated  debentures. This  could lead  to conversion
into shares of VLSI Common Stock, either voluntary or in response to a call  for
redemption by the Company. Sales of large numbers of shares by Intel, optionees,
holders  of convertible debentures  who convert into Common  Stock or others may
have a depressing effect on the market price for the Company's Common Stock. See
"Capitalization."

                                USE OF PROCEEDS

    The net proceeds to the Company from the sale of Common Stock offered hereby
are estimated to be approximately $61,587,500 ($70,874,375 if the  Underwriters'
over-allotment option is exercised in full). The proceeds will be used primarily
for  adding internal or external wafer  fabrication capacity. In particular, the
Company intends to install additional manufacturing equipment and build out  the
third  of  four modules  in  its San  Antonio  fabrication facility  to increase
manufacturing capacity. Although the  Company does not  currently intend to  use
the  proceeds of this offering for the  acquisition of the business, products or
technologies of other companies, it may in the future enter into agreements  for
such  acquisitions. There are  no pending agreements  or arrangements concerning
material acquisitions. Pending such uses, the  net proceeds will be invested  in
investment grade securities.

                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY

    The  Company's Common Stock  has been traded  on the over-the-counter market
under the Nasdaq  Stock Market symbol  VLSI since the  Company's initial  public
offering in 1983. The following table sets forth, for the periods indicated, the
high and low closing prices for the Common Stock on the Nasdaq Stock Market. The
last  reported sale price for the Common Stock of the Company on June 6, 1995 as
reported by the  Nasdaq Stock  Market is  set forth on  the cover  page of  this
Prospectus.  At March 31,  1995, the Company had  approximately 1,695 holders of
record of its  Common Stock and  36,871,246 shares outstanding.  See also  "Risk

                                    BUSINESS

    VLSI is  a leader  in the  design, manufacture  and sale  of highly  complex
application specific integrated circuits ("ASICs")--custom designed chips for an
individual customer--and application specific standard products
("ASSPs")--semi-custom  chips designed for a  particular market application that
may be  used by  several different  customers. The  Company targets  high-volume
markets  in which it has built significant  expertise and can use its library of
proprietary cells and highly integrated  building blocks to assist customers  in
designing  products and bringing  them to market  rapidly. VLSI's target markets
include the computing,  communications and consumer  and entertainment  markets.
VLSI  emphasizes high performance  applications where its  products are critical
elements of complex electronic systems. VLSI  targets key OEM customers who  are
leaders  in their respective  industries. The Company's  major customers include
Compaq, Apple, Ericsson, Hewlett-Packard, Tellabs, Alcatel and Silicon Graphics.

    VLSI produces  a significant  portion of  its wafers  (approximately 73%  in
1994)  at its own  facilities and augments  internal manufacturing capacity with
the foundry services  of third-party subcontractors.  The Company believes  that
this strategy improves quality, cost-effectiveness, responsiveness to customers,
access  to capacity,  ability to implement  leading edge  process technology and
time to market,  as compared  to semiconductor companies  that lack  fabrication
facilities.  The semiconductor  industry is, however,  currently facing capacity
constraints in wafer  manufacturing and  the availability  of third-party  wafer
foundries  has  diminished  significantly. Due  to  this  manufacturing capacity
shortage, as  well as  increased  customer demand,  the  Company is  seeking  to
accelerate   the  expansion   and  upgrading   of  its   internal  and  external
manufacturing capacity.

    Through its subsidiary,  COMPASS Design Automation,  Inc. ("COMPASS"),  VLSI
offers  an  integrated suite  of electronic  design automation  ("EDA") software
tools, foundry-flexible libraries and  support services for  use by systems  and
circuit  designers at other  semiconductor and systems companies,  as well as at
the Company, in creating complex integrated circuits.

BUSINESS STRATEGY

    VLSI's objective  is to  design and  manufacture highly-integrated,  complex
semiconductor  devices that allow  its customers to develop  and bring to market
higher value-added systems and products. Key elements in its strategy to achieve
this objective include:

    - TARGET HIGH-VOLUME MARKETS. VLSI targets  high-volume markets in which  it
      has built significant expertise and can utilize its library of proprietary
      cells  and high-level building blocks to assist customers in designing and
      bringing the customers'  products to  market rapidly.  VLSI believes  that
      this  allows the  Company to  offer more value  to the  customer at higher
      gross margins for the Company.

    - FOCUS  ON  LARGE,  INDUSTRY-LEADING   OEM  CUSTOMERS.  VLSI  focuses   its
      manufacturing  and research and development  resources on products for OEM
      customers that are  leaders in their  respective industries. During  1994,
      approximately  two-thirds of the Company's  net revenues were derived from
      sales  to  its  top  20  customers,  including  Compaq,  Apple,  Ericsson,
      Hewlett-Packard, Tellabs, Alcatel and Silicon Graphics.

    - EMPHASIZE  STANDARD CELL  ASICS AND  ASSPS. VLSI  emphasizes standard cell
      ASICs and ASSPs as compared to gate arrays and other design methodologies.
      The Company  believes  that  the  standard cell  approach  is  a  superior
      methodology  for satisfying  the size,  performance and  power consumption
      requirements of  the  highly  complex products  that  form  VLSI's  target
      markets.

    - LEVERAGE  LIBRARY OF STANDARD  CELLS TO REDUCE  CUSTOMERS' TIME TO MARKET.
      VLSI's Functional System Block ("FSB") library, an expanding collection of
      pre-designed cells  and high-level  building blocks,  provides  frequently
      used  integrated circuit  functions. The FSB  library allows  VLSI and its
      customers to more rapidly design and integrate products, thereby  reducing
      VLSI's customers' time to market. VLSI's library of FSBs includes Graphics
      Controllers  (LCD  and  CRT),  a  DES  Encryption  FSB,  a  PCI  FSB, SCSI
      Controllers, an ARM RISC-based microprocessor (low

                                       13
<PAGE>
      power, high performance embedded control applications), power  management,
      communications  (including  standards such  as  DECT, CT2,  GSM  and PHS),
      signal converters, forward error  correction, digital demodulation,  MPEG2
      and digital signal processing.

    - PROVIDE  ENGINEERING DESIGN  SUPPORT. The  Company seeks  to differentiate
      itself from its competitors not only through the quality of its  products,
      but  also through the level of its technological support and service. VLSI
      operates a network  of geographically dispersed  Technology Centers  where
      experienced  engineers with a specific technical focus work with customers
      to develop designs for new  products and to provide continuing  after-sale
      customer support. In 1993, VLSI established a Customer Excellence program,
      which  is designed to foster relationships  with customers through the use
      of teams focused on elements such as customer satisfaction,  manufacturing
      competence and technical excellence.

    - EMPLOY  BOTH INTERNAL AND EXTERNAL MANUFACTURING CAPACITY. VLSI produces a
      significant portion of its wafers (approximately  73% in 1994) at its  own
      facilities  and augments internal manufacturing  capacity with the foundry
      services of third-party  wafer subcontractors. The  Company believes  that
      this  strategy  improves  quality,  cost-effectiveness,  responsiveness to
      customers, access to capacity, ability  to implement leading edge  process
      technology and time to market, as compared to semiconductor companies that
      lack  fabrication  facilities.  The  semiconductor  industry  is, however,
      currently facing  capacity  constraints  in wafer  manufacturing  and  the
      availability  of third-party wafer foundries has diminished significantly.
      Due to this manufacturing capacity shortage, as well as increased customer
      demand, the Company is seeking  to accelerate the expansion and  upgrading
      of its internal and external manufacturing capacity.

                              RECENT DEVELOPMENTS

SALE OF STOCK BY INTEL

    In January and February 1995, Intel sold an aggregate of 5,355,207 shares of
Common  Stock of  the Company  that it had  acquired pursuant  to the Intel/VLSI
Stock and Warrant Purchase Agreement dated July  8, 1992. As a result, Intel  is
no  longer a  stockholder of  the Company, although  it currently  holds a fully
exercisable warrant to purchase an aggregate of 2,677,604 shares of Common Stock
at an exercise price of $11.69 per share and expiring in August 1995. See  "Risk
Factors--Effect of Potential Stock Sales."

DEVELOPMENT OF 0.35-MICRON PROCESS TECHNOLOGY WITH HITACHI

    In  April 1995, the Company and Hitachi announced the joint development of a
new 0.35-micron process technology for ASICs. The Company believes that the  new
process  technology will be used for  ASICs in the computing, communications and
consumer and  entertainment  markets.  The  Company's  development  and  initial
fabrication  of  ASICs using  the  0.35-micron process  is  taking place  at the
Company's San Antonio, Texas facility. The Company and Hitachi are parties to  a
joint  development  agreement for  the  development of  0.35-micron  and smaller
geometry process  technologies, which  expires  in 1997.  See "Risk  Factors  --
Manufacturing Risks."

TI LITIGATION

    In  July 1990, Texas  Instruments filed two actions  against the Company and
four other defendants, Analog Devices, Inc., Integrated Device Technology,  Inc.
("IDT"),  LSI  Logic  Corporation  and  Cypress  Semiconductor  Corporation (the
Company and  such other  defendants  are collectively  referred  to as  the  "TI
Defendants"). IDT settled its cases with TI in late December 1992.

    In  the action filed before the United States International Trade Commission
("ITC"), TI sought to exclude from importation into the U.S. all TI  Defendants'
products  manufactured  outside  the  U.S.  that  allegedly  utilize  a  plastic
encapsulation process described in U.S. Patent No. 4,043,027 (the "027 patent").
On October 15, 1991, the Administrative  Law Judge ("ALJ") found the 027  patent
to  be valid  and infringed  by the  Company's old  plastic encapsulation gating
process. However, a new plastic encapsulation gating process developed and  used
by the TI Defendants was found not to infringe the 027 patent. In December 1991,
the  full ITC determined that it would  not consider TI's appeal to overturn the
ALJ's decision on noninfringement of the new process. The United States Court of
Appeals for the Federal Circuit affirmed the ITC decision in March 1993. The 027
patent has since expired.

    TI also filed a patent infringement action against the TI Defendants in  the
United  States  District Court  for the  Northern District  of Texas  seeking an
injunction against the sale and/or manufacture by the TI Defendants of  products
that  allegedly  infringe the  027 patent.  The action  also sought  damages for
alleged past infringement  of the  027 patent and  now expired  U.S. Patent  No.
43,716,764.  A trial for this matter was held in April 1995, which resulted in a
May 1995 verdict against VLSI for $19.4 million. The Company intends to  contest
the  verdict. However,  the Company  will record a  charge to  earnings of $19.4
million in the  second quarter of  1995. Based  on the jury's  finding that  the
alleged  infringement was intentional, TI may  also request that the judge award
treble damages. In the event that treble damages are awarded, the judgment could
result in a material reduction in liquidity,  as well as an increased impact  on
the Company's reported results of operations.

may exercise such option only to cover over-allotments in the sale of the shares
of Common Stock  that the Underwriters  have agreed to  purchase. To the  extent
that  the Underwriters exercise  such option, each Underwriter  will have a firm
commitment, subject to certain conditions, to purchase option shares in the same
proportion as the number of shares of  Common Stock to be purchased and  offered
by  such Underwriter in the  table above bears to the  total number of shares of
Common Stock initially offered by the Underwriters hereby.

                                       17

    The Company has agreed that it  will not, without the prior written  consent
of Salomon Brothers Inc, sell, offer or contract to sell or otherwise dispose of
directly  or indirectly (except  as required upon the  exercise of warrants), or
announce the  offering  of,  any  shares  of  Common  Stock  or  any  securities
convertible  into,  or  exchangeable  for, Common  Stock,  except  those offered
hereby, for a period of 90 days from the date of the Underwriting Agreement. The
foregoing notwithstanding,  the Company  may during  such period  issue or  sell
shares  of its Common Stock pursuant to  the Company's existing stock option and
stock purchase plans. Furthermore, all  directors and executive officers of  the
Company  have agreed  that they  will not  offer, sell  or contract  to sell, or
otherwise dispose of, any shares  of Common Stock for a  period of 90 days  from
the  date of  the Underwriting  Agreement without  the prior  written consent of
Salomon Brothers Inc (other than shares disposed of as BONA FIDE gifts or shares
of Common Stock delivered to the Company  in order to exercise, but not  dispose
of shares of Common Stock received pursuant to the exercise of, stock options).

    In  connection  with the  offering, certain  Underwriters and  selling group
members who are  qualifying registered  market makers  on Nasdaq  may engage  in
passive  market-making transactions in the Common  Stock on Nasdaq in accordance
with Rule  10b-6A under  the Exchange  Act during  the two  business day  period
before  commencement of  offers or  sales of the  Common Stock  in the offering.
Passive market making  transactions must  comply with certain  volume and  price
limitations  and be identified as  such. In general, a  passive market maker may
display its bid at a price not in excess of the highest independent bid for  the
security,  and  if all  independent bids  are lowered  below the  passive market
maker's bid, then  such bid  must be lowered  when certain  purchase limits  are
exceeded.

    The  Underwriting  Agreement provides  that the  Company will  indemnify the
several Underwriters against  certain liabilities,  including liabilities  under
the  Act, or contribute to payments the  Underwriters may be required to make in
respect thereof.

                                 LEGAL MATTERS

Company  by Wilson, Sonsini,  Goodrich & Rosati,  Professional Corporation, Palo
Alto, California, and for the Underwriters  by Latham & Watkins, San  Francisco,

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The Company has the power, pursuant  to Section 145 of the Delaware  General
Corporation  Law, to limit the liability of directors to the Company for certain
breaches of fiduciary duty  and to indemnify its  directors, officers and  other
persons  for certain acts. The  Company's Restated Certificate of Incorporation,
as amended, includes the following provision:

    "11.  LIMITATION OF DIRECTORS' LIABILITY.   To the fullest extent  permitted
    by  the Delaware  General Corporation Law  as the  same exists or  as it may
    hereafter be amended, a director of the Corporation shall not be  personally
    liable  to  the Corporation  or its  stockholders  for monetary  damages for
    breach of fiduciary duty as a director. Neither any amendment nor repeal  of
    this  Article 11, nor the  adoption of any provision  of this Certificate of
    Incorporation inconsistent with this Article  11, shall eliminate or  reduce
    the  effect of this  Article 11 in  respect of any  matter occurring, or any
    cause of action, suit or claim that,  but for this Article 11, would  accrue
    or  arise, prior  to such amendment,  repeal or adoption  of an inconsistent
    provision."

    Article VI of  the Bylaws  of the Company  provides that  the Company  shall
indemnify  certain agents of  the Company against  judgments, fines, settlements
and other  expenses arising  from  such person's  agency relationship  with  the
Company  provided that  the standard  of conduct set  forth therein  is met. The
effect of Article VI is to  require that the Company provide indemnification  to
such  agents to the maximum extent permitted by the Delaware General Corporation
Law. Agents covered by this indemnification provision include current and former
directors and officers  of the  Company, as  well as  persons who  serve at  the
request  of the Company  as directors, officers, employees  or agents of another
enterprise.

    In addition, the  Company has entered  into indemnification agreements  with
each  of  its  directors  and  certain  of  its  officers.  The  indemnification
agreements are based on  the provisions of Section  145 of the Delaware  General
Corporation Law and attempt to provide the directors and officers of the Company
with  the  maximum  indemnification  allowed  under  Delaware  law.  In  certain
instances, they  may  result  in  an expansion  of  the  substantive  protection
available  to such individuals  under the Restated  Certificate of Incorporation
and the Bylaws.

    The  Company  currently   maintains  directors'   and  officers'   liability
insurance,  but the  policy does  not provide  coverage for  liabilities arising
under the Securities Act.

    Reference is also made to Section 8 of the Underwriting Agreement  contained
in  Exhibit 1.1  hereto, indemnifying officers  and directors  of the Registrant
against certain liabilities.

ITEM 17.  UNDERTAKINGS

    The  undersigned  Registrant  hereby   undertakes  that,  for  purposes   of
determining  any liability under the Securities Act  of 1933, each filing of the
Registrant's annual report  pursuant to Section  13(a) or Section  15(d) of  the
Securities  Exchange  Act  of 1934  that  is  incorporated by  reference  in the
Registration Statement  shall  be deemed  to  be a  new  Registration  Statement
relating  to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

    Insofar as indemnification for liabilities arising under the Securities  Act
of  1933 may be permitted to directors,  officers and controlling persons of the
Registrant pursuant to provisions described in Item 15 hereof or otherwise,  the
Registrant  has been advised that in the  opinion of the Securities and Exchange

                                      II-2
<PAGE>
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for  indemnification
against  such liabilities (other than the  payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the  Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled  by controlling  precedent, submit  to a  court of  appropriate
jurisdiction  the  question of  whether such  indemnification  by it  is against
public policy  as  expressed in  the  Act and  will  be governed  by  the  final
adjudication of such issue.

    The undersigned Registrant hereby undertakes that:

        (1)  For purposes of determining any  liability under the Securities Act
    of 1933, the information omitted from  the form of Prospectus filed as  part
    of this Registration Statement in reliance upon Rule 430A and contained in a
    form of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4)
    or  497(h)  under the  Securities Act  shall be  deemed to  be part  of this
    Registration Statement as of the time it was declared effective.

        (2) For the purpose  of determining any  liability under the  Securities
    Act  of  1933,  each  post-effective  amendment  that  contains  a  form  of
    Prospectus shall be deemed  to be a new  Registration Statement relating  to
    the  securities offered therein, and the offering of such securities at that
    time shall be deemed to be the initial bona fide offering thereof.

become effective.  Prior to the termination of the offering of the Securities,
the Company will not file any amendment to the Registration Statement or
supplement to the Prospectus unless the Company has furnished you a copy for
your review prior to filing and will not file any such proposed amendment or
supplement to which you reasonably object.  Subject to the foregoing sentence,
if the Registration Statement has become or becomes effective pursuant to Rule
430A, or filing of the Prospectus is


                                        9
<PAGE>

otherwise required under Rule 424(b), the Company will cause the Prospectus,
properly completed, and any supplement thereto to be filed with the Commission
pursuant to the applicable paragraph of Rule 424(b) within the time period
prescribed and will provide evidence satisfactory to the Representatives of such
timely filing.  The Company will promptly advise the Representatives (i) when
the Registration Statement, if not effective at the Execution Time, and any
amendment thereto, shall have become effective, (ii) when the Prospectus, and
any supplement thereto, shall have been filed (if required) with the Commission
pursuant to Rule 424(b), (iii) when, prior to termination of the offering of the
Securities, any amendment to the Registration Statement shall have been filed or
become effective, (iv) of any request by the Commission for any amendment to the
Registration Statement or supplement to the Prospectus or for any additional
information, (v) of the issuance by the Commission of any stop order suspending
the effectiveness of the Registration Statement or the institution or
threatening of any proceeding for that purpose and (vi) of the receipt by the
Company of any notification with respect to the suspension of the qualification
of the Securities for sale in any jurisdiction or the initiation or threatening
of any proceeding for such purpose.  The Company will use its best efforts to
prevent the issuance of any such stop order and, if issued, to obtain as soon as
possible the withdrawal thereof.

          (b)    If, at any time when a prospectus relating to the Securities is
required to be delivered under the Act, any event occurs as a result of which
the Prospectus as then supplemented would include any untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, or if it shall be necessary to amend the Registration
Statement or supplement the Prospectus to comply with the Act or the Exchange
Act or the respective rules thereunder, the Company promptly will prepare and
file with the Commission, subject to the second sentence of paragraph (a) of
this Section 5, an amendment or supplement that will correct such statement or
omission or effect such compliance.

          (c)    As soon as practicable, the Company will make generally
available to its securityholders and to the Representatives an earnings
statement or statements of the Company and its subsidiaries that will satisfy
the provisions of Section 11(a) of the Act and Rule 158 under the Act.

          (d)    The Company, without charge, will furnish to counsel for
the Underwriters a signed copy of the Registration Statement (including exhibits
thereto), to each Representative a copy of the Registration Statement (including
exhibits thereto) and to each other Underwriter a copy of the Registration
Statement (without exhibits thereto) and, so long as delivery of a prospectus by
an Underwriter or dealer may be required by the Act, as many copies of each
Preliminary Prospectus and the Prospectus and any supplement thereto as the
Representatives may reasonably request.  The Company will pay the expenses of
printing or other production of all documents relating to the offering.

          (e)    The Company will arrange for the qualification of the
Securities for sale under the laws of such jurisdictions as the Representatives
may designate, will maintain such


                                       10
<PAGE>

qualifications in effect so long as required for the distribution of the
Securities and will pay the fee of the National Association of Securities
Dealers, Inc. (the "NASD"), in connection with its review of the offering.

          (f)    The Company will not, for a period of 90 days following the
Execution Time, without the prior written consent of Salomon Brothers Inc
offer, sell or contract to sell, or otherwise dispose of, directly or
indirectly, or announce the offering of, any other shares of capital stock of
the Company or any securities convertible into, or exchangeable for, shares of
capital stock of the Company; PROVIDED, HOWEVER, that the Company may issue and
sell Common Stock pursuant to any employee or director stock option or purchase
plan of the Company in effect at the Execution Time and the Company may issue
Common Stock issuable upon the exercise of options or warrants outstanding at
the Execution Time.

          (g)    The Company either has caused to be delivered to the
Representatives or will cause to be delivered to the Representatives prior to
the effective date of the Registration Statement a letter from each of the
Company's directors and executive officers stating that such person agrees that
he or she will not for a period of 90 days following the Execution Time, without
the prior written consent of Salomon Brothers Inc, offer, sell, contract to
sell or otherwise dispose of any shares of capital stock of the Company or any
securities convertible into or exchangeable for, shares of capital stock of the
Company (other than such securities disposed of as bona fide gifts or
delivered to the Company in order to exercise, but not dispose of shares of
Common Stock received pursuant to the exercise of, stock options pursuant to
the terms of such stock options).

          (h)    The Company will not incur any liability for any finder's or
broker's fee or agent's commission in connection with the execution and delivery
of this Agreement or the consummation of the transactions contemplated hereby.

          (i)    The Company will inform the Florida Department of Banking and
Finance at any time prior to the consummation of the distribution of the
Securities by the Underwriters if it commences engaging in business with the
government of Cuba or with any person or affiliate located in Cuba.  Such
information will be provided within 90 days after the commencement thereof or
after a change occurs with respect to previously reported information.

          (j)    The Company agrees to notify the Nasdaq National Market of the
offering of Securities and to pay the fees required by Schedule D to the NASD
By-Laws in connection therewith.

          6.     CONDITIONS TO THE OBLIGATIONS OF THE UNDERWRITERS.  The
obligations of the Underwriters to purchase the Underwritten Securities and the
Option Securities, as the case may be, shall be subject to the accuracy of the

3 hereof, to the accuracy of the statements of the Company made in any
certificates pursuant to the provisions hereof, to the performance by the
Company of its obligations hereunder and to the following additional conditions:

          (a)    If the Registration Statement has not become effective prior to
the Execution Time, unless the Representatives agree in writing to a later time,
the Registration Statement will become effective not later than (i) 6:00 p.m.
New York City time, on the date of determination of the public offering price,
if such determination occurred at or prior to 3:00 p.m. New York City time on
such date or (ii) 12:00 Noon on the business day following the day on which the
public offering price was determined, if such determination occurred after
3:00 p.m. New York City time on such date; if filing of the Prospectus, or any
supplement thereto, is required pursuant to Rule 424(b), the Prospectus, and any
such supplement, will be filed in the manner and within


                                       11
<PAGE>

the time period required by Rule 424(b); and no stop order suspending the
effectiveness of the Registration Statement shall have been issued and no
proceedings for that purpose shall have been instituted or threatened.

          (b)    The Company shall have furnished to the Representatives the
opinion of Wilson, Sonsini, Goodrich & Rosati, counsel for the Company, dated

          (i)    each of the Company and COMPASS has been duly incorporated and
     is validly existing as a corporation in good standing under the laws of the
     jurisdiction in which it is chartered or organized, with full corporate
     power and authority to own its properties and conduct its business as
     described in the Prospectus;

          (ii)   the Company's authorized capital stock is as set forth in the
     Prospectus; the capital stock of the Company conforms to the description
     thereof contained in the Registration Statement; the Securities have been
     duly and validly authorized, and, when issued and delivered to and paid for

     Securities are in valid and sufficient form;

          (iii)  this Agreement has been duly authorized, executed and delivered
     by the Company;

         (iv)   neither the issue and sale of the Securities, nor the
     consummation of any other of the transactions herein contemplated nor the
     fulfillment of the terms hereof will conflict with, result in a breach or
     violation of, or constitute a default under (A) the charter or by-laws of
     the Company or (B) the terms of the Intel/VLSI Stock and Warrant Purchase
     Agreement dated July 8, 1992, the Warrant dated August 25, 1992, issued to
     Intel Corporation or the Indenture dated as of May 1, 1987 by and between
     the Company and Citibank, N.A., as trustee, with respect to the Company's
     7% Convertible Subordinated Debentures due May 1, 2012 or (C) any material
     judgment, order or decree known to such counsel to be applicable to the
     Company or COMPASS of any court, regulatory body, administrative agency,
     governmental body or arbitrator having jurisdiction over the Company or
     COMPASS;

          (v)    no consent, approval, authorization or order of any third party
     (whether acting in an individual, fiduciary or other capacity) or of any
     court or governmental agency or body is required for the issue and sale of
     the Securities or the consummation of the transactions contemplated herein,
     except such as have been obtained under the Act and such as may be required
     under the blue sky laws of any jurisdiction in connection with the purchase
     and distribution of the Securities by the Underwriters and such other
     approvals (specified in such opinion) as have been obtained;

<PAGE>

          (vi)   the Company is not, and upon receipt and pending application of
     the net proceeds from the sale of the Common Stock in the manner described
     in the Prospectus will not be, an "investment company" or a company
     "controlled" by an investment company within the meaning of the Investment
     Company Act of 1940, as amended;

          (vii)  the documents incorporated by reference in the Prospectus or
     any further amendment or supplement thereto made by the Company prior to
     such Closing Date (other than the financial statements and related
     schedules and other financial and statistical information contained
     therein, as to which such counsel need express no opinion), when they
     became effective or were filed with the Commission, as the case may be
     (unless such documents have thereafter been amended, in which case when so
     amended), complied as to form in all material respects with the
     requirements of the Exchange Act and the rules thereunder; and such counsel
     has no reason to believe that any such documents, when such documents
     became effective or were so filed, as the case may be (or if amended, when
     so amended), contained, in the case of documents which were filed under the
     Exchange Act with the Commission, an untrue statement of a material fact or
     omitted to state a material fact necessary in order to make the statements
     therein, in the light of the circumstances under which they were made when
     such documents were so filed (or if amended, when so amended), not
     misleading; and

          (viii) the Registration Statement has become effective under the Act;
     any required filing of the Prospectus, and any supplements thereto,
     pursuant to Rule 424(b) has been made in the manner and within the time
     period required by Rule 424(b); to the best knowledge of such counsel, no
     stop order suspending the effectiveness of the Registration Statement has
     been issued, no proceedings for that purpose have been instituted or
     threatened; and the Registration Statement and the Prospectus (other than
     the financial statements and related schedules and other financial and
     statistical information contained therein, as to which such counsel need
     express no opinion) comply as to form in all material respects with the
     applicable requirements of the Act and the Exchange Act and the respective
     rules thereunder.

     In addition, such counsel shall state that such counsel has no reason to
     believe that at the Effective Date the Registration Statement contained any
     untrue statement of a material fact or omitted to state any material fact
     required to be stated therein or necessary to make the statements therein
     not misleading or that the Prospectus, as of its date and as of the Closing
     Date, included or includes any untrue statement of a material fact or
     omitted or omits to state a material fact necessary to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading.

opinion of Thomas C. Tokos, Assistant General Counsel of the Company, dated the
Closing Date, to the effect that:

     and conduct its business as described in the Prospectus, and is duly
     qualified to do business as a foreign corporation and is in good standing
     under the laws of each jurisdiction that requires such qualification
     wherein it owns or leases material properties or conducts material

     the aggregate have a material adverse effect on the Company and its
     subsidiaries considered as a whole;

          (ii)   all the outstanding shares of capital stock of COMPASS and VLSI
     Tech. have been duly and validly authorized and issued and are fully paid

     sufficient form; and the holders of outstanding shares of capital stock of
     the Company are not entitled to preemptive or other rights to subscribe for
     the Securities;

          (iv)   to the knowledge of such counsel, there is no pending or
     threatened in writing action, suit or proceeding before any court or
     governmental agency, authority or body or any arbitrator involving the
     Company or any of its subsidiaries of a character required to be disclosed
     in the Registration Statement which is not adequately disclosed in the
     Prospectus, and there is no franchise, contract or other document of a
     character required to be described in the Registration Statement or
     Prospectus, or to be filed as an exhibit, which is not described or filed
     as required; and the statements in the Prospectus under the headings "Risk

     express an opinion) or (B) the respective charter or by-laws of the
     Company or COMPASS or (C) the terms of any indenture or other material
     agreement or instrument known to such counsel and to which the Company or
     any of its subsidiaries is a party or bound or (D) any material judgment,
     order or decree known to such counsel to be applicable to the Company or
     any of its subsidiaries of any court, regulatory body, administrative
     agency, governmental body or arbitrator having jurisdiction over the
     Company or any of its subsidiaries;

          (vii)  no holders of securities of the Company other than Intel

     as to matters involving the application of laws of any jurisdiction other
     than the State of California or the United States, to the extent they deem
     proper and specified in such opinion, upon the opinion of other counsel of
     good standing whom they believe to be reliable and who are satisfactory to
     counsel for the Underwriters and (B) as to matters of fact, to the extent
     they deem proper, on certificates of responsible officers of the Company
     and public officials.  References to the Prospectus in paragraphs (b) and
     (c) include any supplements thereto at the Closing Date.

          (d)    The Representatives shall have received from Latham & Watkins,
counsel for the Underwriters, such opinion or opinions, dated the Closing Date,
with respect to the issuance and sale of the Securities, the Registration
Statement, the Prospectus (together with any supplement thereto) and other
related matters as the Representatives may reasonably require, and


                                       15
<PAGE>

the Company shall have furnished to such counsel such documents as they request
for the purpose of enabling them to pass upon such matters.

          (e)    The Company shall have furnished to the Representatives a
certificate of the Company, signed by the Chief Executive Officer and the
principal financial or accounting officer of the Company, dated the Closing
Date, to the effect that the signers of such certificate have carefully
examined the Registration Statement, the Prospectus, any supplement to the
Prospectus and this Agreement and that:

          (i)    the representations and warranties of the Company in this
     Agreement are true and correct in all material respects on and as of the
     Closing Date with the same effect as if made on the Closing Date and the
     Company has complied with all the agreements and satisfied all the
     conditions on its part to be performed or satisfied at or prior to the
     Closing Date;

          (ii)   no stop order suspending the effectiveness of the Registration
     Statement has been issued and no proceedings for that purpose have been
     instituted or, to the Company's knowledge, threatened; and

          (iii)  since the date of the most recent financial statements included
     in the Prospectus (exclusive of any supplement thereto), there has been no
     material adverse change in the condition (financial or other), earnings,
     business or properties of the Company and its subsidiaries, whether or not
     arising from transactions in the ordinary course of business, except as set
     forth in or contemplated in the Prospectus (exclusive of any supplement
     thereto).

          (f)    At the Execution Time and at the Closing Date, Ernst & Young
LLP shall have furnished to the Representatives a letter or letters, dated
respectively as of the Execution Time and as of the Closing Date, in form and
substance satisfactory to the Representatives, confirming that they are
independent accountants within the meaning of the Act and the Exchange Act and
the respective applicable published rules and regulations thereunder and stating
in effect that:

          (i)    in their opinion the audited financial statements and financial
     statement schedules included or incorporated in the Registration Statement
     and the Prospectus and reported on by them comply in form in all material
     respects with the applicable accounting requirements of the Act and the
     Exchange Act and the related published rules and regulations;

          (ii)   on the basis of a reading of the latest unaudited financial
     statements made available by the Company and its subsidiaries; carrying out
     certain specified procedures (but not an examination in accordance with
     generally accepted auditing standards) which would not necessarily reveal
     matters of significance with respect to the comments set forth in such
     letter; a reading of the minutes of the meetings of the stockholders,
     directors and


                                       16
<PAGE>

     compensation and audit committees of the Company; and inquiries of certain
     officials of the Company who have responsibility for financial and
     accounting matters of the Company and its subsidiaries as to transactions
     and events subsequent to December 30, 1994, nothing came to their attention
     that caused them to believe that:

               (1)  any unaudited financial statements included or
          incorporated in the Registration Statement and the Prospectus do
          not comply in form in all material respects with applicable
          accounting requirements and with the published rules and
          regulations of the Commission with respect to financial
          statements included or incorporated by reference in quarterly
          reports on Form 10-Q under the Exchange Act; and said unaudited
          financial statements are not in conformity with generally
          accepted accounting principles applied on a basis substantially
          consistent with that of the audited financial statements included
          or incorporated by reference in the Registration Statement and
          the Prospectus; or

               (2)  with respect to the period subsequent to March 31,
          1995, there were any changes, at a specified date not more than
          five business days prior to the date of the letter, in the long-
          term debt, including non-current capital lease obligations, of
          the Company and its subsidiaries or capital stock of the Company
          or decreases in the stockholders' equity or total current assets
          of the Company as compared with the amounts shown on the March
          31, 1995 consolidated balance sheet included or incorporated by
          reference in the Registration Statement and the Prospectus, or
          for the period from March 31, 1995 to such specified date there
          were any decreases, as compared with the corresponding period in
          the preceding year in net revenues or income before income taxes
          or in total or per share amounts of income before extraordinary
          items or net income of the Company and its subsidiaries, except
          in all instances for changes or decreases set forth in such
          letter, in which case the letter shall be accompanied by an
          explanation by the Company as to the significance thereof unless
          said explanation is not deemed necessary by the Representatives;
          and

          (iii)  they have performed certain other specified procedures as a
     result of which they determined that certain information of an accounting,
     financial or statistical nature (which is limited to accounting, financial
     or statistical information derived from the general accounting records of
     the Company and its subsidiaries) set forth in the Registration Statement
     and the Prospectus, including the information set forth under the captions
     "Prospectus Summary -- Summary Consolidated Financial Data,"
     "Capitalization" and "Selected Consolidated Financial Data" in the
     Prospectus, the information included or incorporated by reference in the
     Company's Annual Report on Form 10-K for the fiscal year ended December 30,
     1994, incorporated by


                                       17
<PAGE>

     reference in the Registration Statement and the Prospectus, and the
     information included in the Management's Discussion and Analysis of
     Financial Condition and Results of Operations, included or incorporated by
     reference in the Company's Quarterly Report on Form 10-Q for the quarter
     ended March 31, 1995, incorporated by reference in the Registration
     Statement and the Prospectus, agrees with the accounting records of the
     Company and its subsidiaries, excluding any questions of legal
     interpretation.

          References to the Prospectus in this paragraph (f) include any
supplement thereto at the date of the letter.

          (g)    Subsequent to the Execution Time or, if earlier, the dates as
of which information is given in the Registration Statement (exclusive of any
amendment thereof) and the Prospectus (exclusive of any supplement thereto),
there shall not have been (i) any change or decrease specified in the letter or
letters referred to in paragraph (f) of this Section 6 or (ii) any change, or
any development involving a prospective change, in or affecting the business or
properties of the Company and its subsidiaries the effect of which, in any case
referred to in clause (i) or (ii) above, is, in the judgment of the
Representatives, so material and adverse as to make it impractical or
inadvisable to proceed with the offering or delivery of the Securities as
contemplated by the Registration Statement (exclusive of any amendment thereof)
and the Prospectus (exclusive of any supplement thereto).

          (h)    Prior to the Closing Date, the Company shall have furnished to
the Representatives such further information, certificates and documents as the
Representatives may reasonably request.

          If any of the conditions specified in this Section 6 shall not have
been fulfilled in all material respects when and as provided in this Agreement,
or if any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form
and substance to the Representatives and counsel for the Underwriters, this
Agreement and all obligations of the Underwriters hereunder may be canceled at,
or at any time prior to, the Closing Date by the Representatives.  Notice of
such cancellation shall be given to the Company in writing or by telephone or
telegraph confirmed in writing.

          7.     REIMBURSEMENT OF UNDERWRITERS' EXPENSES.  If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 6 hereof is not satisfied,
because of any termination pursuant to Section 10 hereof or because of any
refusal, inability or failure on the part of the Company to perform any
agreement herein or comply with any provision hereof other than by reason of a
default by any of the Underwriters, the Company will reimburse the Underwriters
severally upon demand for all out-of-pocket expenses (including reasonable fees
and disbursements of counsel) that shall have been incurred by them in
connection with the proposed purchase and sale of the Securities.

          8.     INDEMNIFICATION AND CONTRIBUTION.

          (a)    The Company agrees to indemnify and hold harmless each
Underwriter, the directors, officers, employees and agents of each Underwriter
and each person who controls any Underwriter within the meaning of either the
Act or the Exchange Act against any and all losses, claims, damages or
liabilities, joint or several, to which they or any of them may become subject
under the Act, the Exchange Act or other Federal or state statutory law or
regulation, at common law or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement of a material fact contained in
the registration statement for the registration of the Securities as originally
filed or in any amendment thereof, or in any Preliminary Prospectus or the
Prospectus, or in any amendment thereof or supplement thereto, or arise out of
or are based upon the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, and agrees to reimburse each such indemnified party, as
incurred, for any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability or action; PROVIDED, HOWEVER, that the Company will not be liable in
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon any such untrue statement or alleged untrue
statement or omission or alleged omission made therein in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
any Underwriter through the Representatives specifically for inclusion therein.
This indemnity agreement will be in addition to any liability that the Company
may otherwise have.

          (b)    Each Underwriter severally agrees to indemnify and hold
harmless the Company, each of its directors, each of its officers, employees and
agents and each person who controls the Company within the meaning of either the
Act or the Exchange Act, to the same extent as the foregoing indemnity from the
Company to each Underwriter, but only with reference to written information
relating to such Underwriter furnished to the Company by or on behalf of such
Underwriter through the Representatives specifically for inclusion in the
documents referred to in the foregoing indemnity.  This indemnity agreement will
be in addition to any liability that any Underwriter may otherwise have.  The
Company acknowledges that the statements set forth in the last paragraph of the
cover page and in the first, third and sixth paragraphs under the caption
"Underwriting" in any Preliminary Prospectus and the Prospectus constitute the
only information furnished in writing by or on behalf of the several
Underwriters for inclusion in any Preliminary Prospectus or the Prospectus, and
you, as the Representatives, confirm that such statements are correct.

          (c)    Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 8, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from liability under paragraph (a) or (b) above unless and
to the extent it did not otherwise learn of such action and such failure results
in the forfeiture by the indemnifying party


                                       19
<PAGE>

of substantial rights and defenses and (ii) will not, in any event, relieve the
indemnifying party from any obligations to any indemnified party other than the
indemnification obligation provided in paragraph (a) or (b) above.  The
indemnifying party shall be entitled to appoint counsel of the indemnifying
party's choice at the indemnifying party's expense to represent the indemnified
party in any action for which indemnification is sought (in which case the
indemnifying party shall not thereafter be responsible for the fees and expenses
of any separate counsel retained by the indemnified party or parties except as
set forth below); PROVIDED, HOWEVER, that such counsel shall be satisfactory to
the indemnified party.  Notwithstanding the indemnifying party's election to
appoint counsel to represent the indemnified party in an action, the indemnified
party shall have the right to employ separate counsel (including local counsel),
and the indemnifying party shall bear the reasonable fees, costs and expenses of
such separate counsel if (i) the use of counsel chosen by the indemnifying party
to represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties that are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party.  An indemnifying party will not, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any pending or threatened claim,
action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless such settlement, compromise or
consent includes an unconditional release of each indemnified party from all
liability arising out of such claim, action, suit or proceeding.

          (d)    In the event that the indemnity provided in paragraph (a) or
(b) of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Underwriters agree to
contribute to the aggregate losses, claims, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or
defending same) (collectively "Losses") to which the Company and one or more of
the Underwriters may be subject in such proportion as is appropriate to reflect
the relative benefits received by the Company and by the Underwriters from the
offering of the Securities; PROVIDED, HOWEVER, that in no case shall any
Underwriter (except as may be provided in any agreement among underwriters
relating to the offering of the Securities) be responsible for any amount in
excess of the underwriting discount or commission applicable to the Securities
purchased by such Underwriter hereunder.  If the allocation provided by the
immediately preceding sentence is unavailable for any reason, the Company and
the Underwriters shall contribute in such proportion as is appropriate to
reflect not only such relative benefits but also the relative fault of the
Company and of the Underwriters in connection with the statements or omissions
that resulted in such Losses as well as any other relevant equitable
considerations.  Benefits received by the Company shall be deemed to be equal to
the total net proceeds from the


                                       20
<PAGE>

offering (before deducting expenses), and benefits received by the Underwriters
shall be deemed to be equal to the total underwriting discounts and commissions,
in each case as set forth on the cover page of the Prospectus.  Relative fault
shall be determined by reference to whether any alleged untrue statement or
omission relates to information provided by the Company or the Underwriters.
The Company and the Underwriters agree that it would not be just and equitable
if contribution were determined by pro rata allocation or any other method of
allocation that does not take account of the equitable considerations referred
to above.  Notwithstanding the provisions of this paragraph (d), no person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation.  For purposes of this Section 8, each person
who controls an Underwriter within the meaning of either the Act or the Exchange
Act and each director, officer, employee and agent of an Underwriter shall have
the same rights to contribution as such Underwriter, and each person who
controls the Company within the meaning of either the Act or the Exchange Act,
each officer of the Company who shall have signed the Registration Statement and
each director of the Company shall have the same rights to contribution as the
Company, subject in each case to the applicable terms and conditions of this
paragraph (d).

          9.     DEFAULT BY AN UNDERWRITER.  If any one or more Underwriters
shall fail to purchase and pay for any of the Securities agreed to be purchased
by such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions that the amount of Securities set
forth opposite their names in Schedule I hereto bears to the aggregate amount of
Securities set forth opposite the names of all the remaining Underwriters) the
Securities that the defaulting Underwriter or Underwriters agreed but failed to
purchase; PROVIDED, HOWEVER, that in the event that the aggregate amount of
Securities that the defaulting Underwriter or Underwriters agreed but failed to
purchase shall exceed 10% of the aggregate amount of Securities set forth in
Schedule I hereto, the remaining Underwriters shall have the right to purchase
all, but shall not be under any obligation to purchase any, of the Securities,
and if such nondefaulting Underwriters do not purchase all the Securities, this
Agreement will terminate without liability to any nondefaulting Underwriter or
the Company.  In the event of a default by any Underwriter as set forth in this
Section 9, the Closing Date shall be postponed for such period, not exceeding
seven days, as the Representatives shall determine in order that the required
changes in the Registration Statement and the Prospectus or in any other
documents or arrangements may be effected.  Nothing contained in this Agreement
shall relieve any defaulting Underwriter of its liability, if any, to the
Company and any nondefaulting Underwriter for damages occasioned by its default
hereunder.

          10.    TERMINATION.  This Agreement shall be subject to termination in
the absolute discretion of the Representatives, by notice given to the Company
prior to delivery of and payment for the Securities, if prior to such time (i)
trading in the Company's Common Stock shall have been suspended by the
Commission or the Nasdaq National Market or trading in securities generally on
the New York Stock Exchange or the Nasdaq National Market shall have been
suspended or limited or minimum prices shall have been established on such
Exchange or Market,


                                       21
<PAGE>

(ii) a banking moratorium shall have been declared either by Federal or New York
State authorities or (iii) there shall have occurred any outbreak or escalation
of hostilities, declaration by the United States of a national emergency or war
or other calamity or crisis the effect of which on financial markets is such as
to make it, in the judgment of the Representatives, impracticable or inadvisable
to proceed with the offering or delivery of the Securities as contemplated by
the Prospectus (exclusive of any supplement thereto).

          11.    REPRESENTATIONS AND INDEMNITIES TO SURVIVE.  The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and of the Underwriters set forth in or made pursuant to
this Agreement will remain in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or the Company or any of
the officers, directors, employees, agents or controlling persons referred to in
Section 8 hereof, and will survive delivery of and payment for the Securities.
The provisions of Sections 7 and 8 hereof shall survive the termination or
cancellation of this Agreement.

          12.    NOTICES.  All communications hereunder will be in writing and
effective only on receipt, and, if sent to the Representatives, will be mailed,
delivered or telegraphed and confirmed to them, care of Salomon Brothers Inc, at
Seven World Trade Center, New York, New York, 10048 at attention of the legal
department; or, if sent to the Company, will be mailed, delivered or telegraphed
and confirmed to it at attention of the legal department.

          13.    SUCCESSORS.  This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the
officers, directors, employees, agents and controlling persons referred to in
Section 8 hereof, and no other person will have any right or obligation
hereunder.

          14.    APPLICABLE LAW.  This Agreement will be governed by and
construed in accordance with the laws of the State of New York.

     VLSI TECHNOLOGY, INC., a corporation organized and existing under and by
virtue of the General Corporation Law of the State of Delaware (the

<PAGE>

     RESOLVED FURTHER:   that the following Amendments to the Corporation's
     Restated Certificate of Incorporation are hereby approved by this Board of

          amended to read as follows:

               (a)  CLASSES OF STOCK.  This Corporation is authorized to issue
               two classes of shares designated respectively "Common Shares" and
               "Preferred Shares".  The total number of shares which this
               Corporation shall have the authority to issue is One Hundred Two
               Million (102,000,000), of which One Hundred Million (100,000,000)
               shall be Common Shares and Two Million (2,000,000) shall be

               shall have a par value per share of $.01, and the aggregate par
               value of the Common Shares and the Preferred Shares shall be

               consist in the aggregate of One Million (1,000,000) shares.  The
               first series of Junior Common Stock shall be designated "Series B
               Common Stock" and shall have the rights, preferences, privileges
               and restrictions set forth in subparagraph (e) of this paragraph

222 of the General Corporation Law of the State of Delaware, a majority of the

FIFTH:    The Amendments were duly adopted in accordance with the provisions of
Section 242 of the General Corporation Law of the State of Delaware.

    RE:  REGISTRATION STATEMENT ON FORM S-3

Ladies and Gentlemen:

    We have examined the Registration Statement on Form S-3 proposed to be filed
by  you with the Securities and Exchange Commission on or about June 7, 1995, in
connection with the registration under the  Securities Act of 1933, as  amended,
of 2,875,000 shares of your Common Stock, $0.01 par value (the "Shares"), all of
which are authorized but heretofore unissued, including an over-allotment option
for  375,000 shares held by  the underwriters. The Shares are  to be sold to the
underwriters for resale to the public as described in the Registration Statement
pursuant to the  Underwriting Agreement filed  as Exhibit 1.1  thereto. As  your
outside legal counsel, in connection with this transaction, we have examined the
proceedings  taken or  proposed to  be taken  in connection  with said  sale and
issuance of the Shares.

    It is our opinion  that, upon completion of  the proceedings being taken  or
contemplated  by us,  as your outside  legal counsel,  to be taken  prior to the
issuance of the Shares,  and upon completion of  the proceedings being taken  in
order  to permit  such transactions  to be  carried out  in accordance  with the
securities laws of the  various states where required,  the Shares, when  issued
and  sold  in the  manner referred  to  in the  Registration Statement,  will be
legally and validly issued, fully paid and non-assessable.

    We consent to  the use of  this opinion  as an exhibit  to the  Registration
Statement,  including  the  prospectus  constituting  a  part  thereof,  and any
amendment thereto.

                                          Very truly yours,

                                          WILSON, SONSINI, GOODRICH & ROSATI
