                 SMSC REPORTS RECORD ANNUAL SEMICONDUCTOR REVENUES

   Strong Growth in Year-over-Year Sales of Connectivity & Networking Products

           Fourth Quarter Operating Profit Quadruples From Prior Year


Hauppauge,  NY - April 12,  2004 - Standard  Microsystems  Corporation  (Nasdaq:
SMSC) today  announced  that revenues for the fourth  quarter ended February 29,
2004 were $52.1 million, an increase of approximately 22% over revenues of $42.6
million in the fourth quarter of fiscal 2003.

Gross  profit  percentage  for the  fourth  quarter  of fiscal  2004 was  48.1%,
compared to 45.3% in the previous year's fourth quarter.

Research and development  expenses for the quarter were $10.2 million,  compared
to $8.5 million in the year-ago quarter, and selling, general and administrative
expenses  were $11.1  million,  compared to $9.9  million in last year's  fourth
quarter.  The  year-over-year  increases in operating expenses primarily reflect
investments  in  engineering  and  marketing  personnel,  tooling  costs for new
product  developments and generally  higher expenses  associated with increasing
revenues.

Operating  income in the fourth  quarter of fiscal 2004 was $3.5 million  versus
$0.8 million in the  year-ago  period.  Fourth  quarter  income from  continuing
operations  was $3.4  million,  or $0.17 per  share,  compared  to  income  from
continuing  operations  of $1.1  million,  or $0.06 per share,  in the  year-ago
period.

During the fourth  quarter of fiscal 2004,  SMSC  announced that it had redeemed
the  minority  interest  in SMSC  Japan from  Sumitomo  Metal  Industries,  Ltd.
(Sumitomo).  The  transaction  resulted  in SMSC Japan  becoming a wholly  owned
subsidiary of SMSC and in a Gain on redemption of preferred  stock of subsidiary
of $6.7  million,  or $0.34 per share,  which is reported as a component  of Net
income applicable to common shareholders on the Company's Consolidated Statement
of Operations for the three months ended February 29, 2004.

Cash and liquid  investments at the end of fiscal 2004,  including $15.6 million
with  maturities in excess of one year,  were $173.9  million,  up $12.0 million
from $161.9  million at November 30, 2003,  and up $61.0 million from the end of
the prior fiscal year.  Inventories  at the end of the fiscal year totaled $23.2
million and remain  appropriate  relative to expected demand. The Company has no
bank debt, and book value per share as of February 29, 2004 increased to $14.27,
compared to $12.17 as of February 28, 2003.


Fiscal 2004 Financial Highlights:

o    SMSC posted record annual  semiconductor  product revenues for fiscal 2004,
     up 24% compared to fiscal 2003.
o    Gross profit  percentage  reached 50.8%, or 45.1% without the $22.5 million
     of IP payments from Intel,  versus 44.6% in fiscal 2003, as SMSC  continued
     to increase the analog content in its product line and provide  innovative,
     higher-value features.
o    The  Company  achieved  strong  growth  in  year-over-year  sales  of USB &
     networking  products.  USB sales more than  tripled from the prior year and
     sales of networking products increased by more than 50%.
o    SMSC's total PC I/O sales increased by 14% from fiscal 2003, growing faster
     than the worldwide PC market for the same period.
o    The Company  achieved  operating  income of $28.8 million  compared to $1.1
     million in fiscal 2003.
o    Income from  continuing  operations  increased  to $1.17 per share versus a
     loss of $0.42 per share in the year-ago period.

"We are pleased to report that SMSC posted record annual semiconductor  revenues
in fiscal 2004," said Steven J. Bilodeau,  Chairman and Chief Executive Officer.
"Sales of USB and networking  products showed strong  year-over-year  growth for
both the fourth  quarter and full fiscal year as we delivered a greater  breadth
of products to an increasingly diverse set of customers. In addition,  SMSC's PC
I/O sales  growth  for the year  continued  to outpace  that of the PC  industry
overall."

Mr. Bilodeau added,  "Looking ahead, as we grow the proportion of our non-PC I/O
products,  which grew to 36% of fourth  quarter  product  sales,  we are closing
design wins for applications that are increasingly outside of SMSC's traditional
end markets and are more consumer  driven.  In particular,  we expect  continued
strong sales of  networking  and  connectivity  products in the first quarter of
fiscal 2005, which should result in non-PC I/O revenues growing to approximately
40% of total first quarter product sales."

Fiscal 2004 Business Highlights:

o    Redeemed the minority  interest in SMSC Japan from  Sumitomo,  resulting in
     SMSC Japan becoming a wholly owned subsidiary of SMSC.
o    Announced  that  SMSC  and  Accton  Technology  Corporation  reached  final
     settlement  of an  arbitration  award,  resulting  in SMSC  receiving  cash
     payments totaling approximately $2.7 million.
o    Reported  that SMSC and Intel  Corporation  reached an agreement to enhance
     their  intellectual  property  and  business  relationship.  The  agreement
     provides for an aggregate of $75 million in payments from Intel to SMSC, of
     which $22.5  million was received in fiscal 2004,  and the balance is to be
     paid in quarterly installments through calendar 2008.
o    Announced  three new  single  chip  environmental  monitoring  and  control
     devices  targeting  mobile,  desktop,  workstation,   server  and  embedded
     markets.
o    Announced the  availability  of a new  multi-zone  fan control  device with
     hardware monitoring and acoustic noise reduction features.
o    Won  several  key design  wins  implementing  non-PCI  Ethernet  devices in
     digital  televisions,  set-top  boxes,  digital media  adapters and digital
     video  recorders.  Introduced a new 10/100 Ethernet PHY targeting  embedded
     and consumer electronics applications.
o    SMSC and the European  ARCNET user group  announced the  availability of an
     ARCNET/Ethernet  IP Gateway to allow seamless  connectivity to existing LAN
     networks.
o    Introduced  a new  9-in-1  flash  media  controller  supporting  the higher
     performance Memory Stick PRO technology licensed by Sony.
o    Announced  SMSC's market entry into the high performance USB 2.0 hub market
     with a 4-port low power, high-speed hub.

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.
