         SMSC REPORTS 27% GROWTH IN FOURTH QUARTER FISCAL 2003 REVENUES

                  Fourth Quarter Net Income Exceeds $1 Million
                Posts 20% Growth In Fiscal 2003 Product Revenues


Hauppauge,  N.Y. - April 7, 2003 - Standard  Microsystems  Corporation  (Nasdaq:
SMSC) today  announced  that revenues for the fourth  quarter ended February 28,
2003 increased by 27% to $42.6 million,  compared to $33.5 million in the fourth
quarter of fiscal 2002.

Gross profit  percentage for the fourth quarter of fiscal 2003 grew by more than
four percentage points to 45.3%, compared to 41.2% in the previous year's fourth
quarter.  Research and  development  expenses for the quarter were $8.5 million,
compared to $6.4  million in the  year-ago  quarter,  and  selling,  general and
administrative  expenses  were $9.9  million,  compared to $7.3  million in last
year's fourth quarter.  Amortization of acquired  intangible  assets  associated
with the  acquisition  of Gain  Technology  Corporation  in June 2002,  was $0.4
million in this year's fourth quarter.

Fourth quarter income from continuing  operations was $1.1 million, or $0.06 per
share, compared to $0.8 million, or $0.04 per share, in the year-ago quarter.

"In an industry  suffering  ongoing  economic  hardships,  SMSC's fourth quarter
capped off a year of solid growth.  Success in value  integration and profitably
growing market share enabled SMSC to deliver fourth quarter revenue that was 27%
higher  than the prior  year,"  said  Steven  J.  Bilodeau,  Chairman  and Chief
Executive Officer.  "Our Advanced I/O business contributed  significantly during
the quarter and experienced a 17% increase in revenues over the prior year, with
a particular strength in notebook sales. In large part,  reflective of our focus
on product  diversification,  our Embedded business grew by over 60% versus last
year's fourth quarter, as sales of new USB 2.0 and Ethernet products ramped."

On a GAAP basis, revenues for fiscal 2003 were $155.5 million compared to $159.3
million in fiscal 2002, and SMSC reported a loss from  continuing  operations of
$0.42  per  share in  fiscal  2003  versus a profit  of $0.47  per  share in the
year-ago period.

Due to the  significance of special items recorded earlier in fiscal 2003 and in
fiscal 2002,  SMSC is presenting  certain pro forma  information to facilitate a
comparison of the operating results for both periods.  The special items include
investment impairment charges, restructuring charges associated with SMSC's exit
from  the  PC  chipset  business  and a  special  intellectual  property-related
payment.  Details of the special  items are shown in the  attached  table of pro
forma information.

Full Year Financial Highlights:

- -    Revenues for fiscal 2003 were $155.5  million,  an increase of 20% from pro
     forma   revenues  of  $129.7   million  in  fiscal  2002,   exceeding   the
     semiconductor industry's composite revenue growth of approximately 1%.
- -    Gross profit of 44.6% grew by more than six percentage points compared to a
     pro forma 38.3% in fiscal  2002,  as SMSC  continued to increase the analog
     content in its product line and provide innovative,  higher-value  features
     to cost effectively address its customers' needs.  Reported gross profit in
     fiscal 2002, including special items, was 49.0%.
- -    Pro forma income from continuing  operations of $0.14 per share was a $0.43
     per share improvement over the prior year.
- -    SMSC's balance sheet remains strong with cash and short-term investments at
     February 28, 2003 of $112.9 million,  no bank debt and book value per share
     of $12.17.

"The  dramatic  year-over-year  improvement  in  SMSC's  pro forma  income  from
continuing operations, from a loss of $4.7 million in fiscal 2002 to a profit of
$2.5  million in fiscal  2003,  illustrates  our leverage to earnings as revenue
grows,"  said  Andrew M.  Caggia,  Senior  Vice  President  and Chief  Financial
Officer.  "Our  balance  sheet  remains  strong and we look forward to continued
growth as we enter 2004. "

Commenting on operating  achievements over the last year, Mr. Bilodeau said, "In
addition  to solid  financial  performance,  the  Company  achieved  a number of
milestones  that  enhanced  its ability to grow  profitably.  SMSC  completed an
important  acquisition  that  greatly  broadened  its  technical   capabilities,
significantly  increased market share,  introduced  several products serving new
high  growth  markets,  secured a number of key  design  wins and  upgraded  its
quality certification to the highest ISO standards."

KEY FISCAL 2003 BUSINESS HIGHLIGHTS FOR SMSC:

- -    Completed the acquisition of Gain Technology Corporation,  now known as the
     SMSC Analog Technology  Center.  The acquisition  brought to SMSC a veteran
     analog and mixed-signal development team of 35 engineers and designers with
     an  average of more than ten years  experience.  It  greatly  enhanced  the
     Company's existing analog and mixed-signal capabilities and brought with it
     a depth of talent that  expands the product and market  opportunities  that
     SMSC may pursue in the future.
- -    Announced  the  availability  of  SMSC's  GT3200,  the first in a family of

     customizable  VUSB-HS device controller with SMSC's GT3200 PHY IC to reduce
     product cost and power consumption while  accelerating  time-to-market  for
     products  with  480-Mbps USB  connectivity.
- -    Introduced the USB97C242 Single-Chip Hi-Speed USB Flash Drive Controller, a

     blocks.  The USB97C210  was also the first 6-in-1 Flash Card  Controller to
     receive Hi-Speed USB  certification  from the USB-IF and the first Hi-Speed
     6-in-1 Flash Card Controller in production.
- -    SMSC's USB97C202 Second Generation USB 2.0 Mass Storage Class Controller, a
     USB bridge chip  designed  for use in external  hard disks,  CDRW,  and DVD
     drives, was certified as USB compliant by the USB-IF.
- -    Accelent  Systems Inc.  selected SMSC's  LAN91C111  10/100 non-PCI Ethernet

     PC's,  combining the functionality of a Super I/O, a high-performance  8051
     microprocessor  for keyboard  control and system  management,  as well as a
     shared flash interface.
- -    Introduced  the  LPC47N350   Keyboard  and  System   Controller   with  LPC
     PortSwitch(TM)  Interface  for  legacy-free  notebook  PC's.  The LPC47N350
     interface is a unique,  hot-switchable  external interface that enables the
     design  of  cost-effective,  full-featured  port  replication  and  docking
     solutions.
- -    Introduced the LPC47N237 Controller, an LPC-based I/O targeted for notebook
     PC port  replicators  and docks,  and  companion  product to SMSC's line of

     interface.
- -    Achieved  an  upgrade  to  ISO  9001:2000   certification  by  NSAI,  Inc.,
     demonstrating the Company's commitment to maintaining a world-class quality
     management  system.  According  to  recently  published  statistics,  as of
     mid-February  2003, only 13% of the total number of  registrations in North
     America have been upgraded to ISO 9001:2000.

FORWARD LOOKING STATEMENTS:

Except for historical  information  contained  herein,  the matters discussed in
this  announcement are  forward-looking  statements about expected future events
and financial and operating results that involve risks and uncertainties.  These
include the timely development and market acceptance of new products; the impact
of competitive  products and pricing; the effect of changing economic conditions
in domestic  and  international  markets;  changes in customer  order  patterns,
including loss of key customers,  order  cancellations or reduced bookings;  and
excess or obsolete  inventory  and  variations  in  inventory  valuation,  among
others.  Such  statements  are qualified in their entirety by the inherent risks
and  uncertainties  surrounding  future  expectations  and may not  reflect  the
potential impact of any future acquisitions, mergers or divestitures.

SMSC  competes  in the  semiconductor  industry,  which  has  historically  been
characterized  by intense  competition,  rapid  technological  change,  cyclical
market patterns,  price erosion and periods of mismatched  supply and demand. In
addition,  sales of many of the Company's  products  depend  largely on sales of
personal computers and peripheral devices,  and reductions in the rate of growth
of the PC and Embedded  markets could  adversely  affect its operating  results.

import  regulations and currency  fluctuations,  which may have an effect on its
business.  All  forward-looking  statements speak only as of the date hereof and
are based upon the information  available to SMSC at this time. Such information
is subject to change,  and we will not  necessarily  inform you of such changes.
These and other risks and uncertainties, including potential liability resulting
from  pending  or  future  litigation,  are  detailed  from  time to time in the
Company's  reports  filed  with  the  SEC.  Investors  are  advised  to read the
