                     SMSC REPORTS 26% YEAR-OVER-YEAR GROWTH
                     IN SECOND QUARTER FISCAL 2004 REVENUES

  Posts More than 150% Increase in Income from Continuing Operations Per Share
                              From Year-Ago Period

        Raises Fiscal 2004 Earnings Estimate by 25%, Exclusive of Income
                            from Special IP Payments

Hauppauge, NY - September 16, 2003 - Standard Microsystems  Corporation (Nasdaq:
SMSC) today announced that revenues for the second quarter ended August 31, 2003
of $48.3 million exceeded prior Company estimates, and increased by 26% compared
to $38.3 million in the second quarter of fiscal 2003. This represents the sixth
consecutive quarter of sequential revenue increases.

Gross profit percentage for the second quarter of fiscal 2004 was 44.5% compared
to 44.7% in the previous year's second quarter.

Research and development expenses for the quarter were $9.3 million, compared to
$7.8 million in the year-ago quarter,  and selling,  general and  administrative
expenses  were $10.0  million,  compared to $8.7  million in last year's  second
quarter.  The  year-over-year  increases in operating expenses primarily reflect
investments in engineering and marketing personnel and generally higher expenses
associated with increasing revenues.

Operating  income in the second quarter of fiscal 2004 was $1.9 million,  versus
$0.2 million in the year-ago period.

Second quarter income from continuing  operations was $1.5 million, or $0.08 per
share, an increase of over 150%,  compared to $0.6 million,  or $0.03 per share,
in the year-ago quarter.

Cash and short-term  investments at the end of the second quarter of fiscal 2004
were $122.6 million,  up from $120.9 million at May 31, 2003. The Company has no
bank debt, and book value per share as of August 31, 2003 was $12.41.

"We are very pleased with our second quarter  results.  Boosted by strong demand
across all major product lines,  revenues  significantly  exceeded prior Company
expectations,"  said Steven J. Bilodeau,  Chairman and Chief Executive  Officer.
"In total,  revenues  from desktop and mobile  products  grew by 26% versus last
year's second quarter."

Mr. Bilodeau added,  "The aggregate sales of SMSC's non-PC  products,  including
our USB and networking products, also showed 26% growth, indicating the momentum
we are gaining in our product diversification strategy."

BUSINESS OUTLOOK FOR SMSC:

On September 8, 2003, SMSC and Intel Corporation  (Intel) announced that the two
companies had enhanced their intellectual  property and business  relationships.
As part of this  agreement,  SMSC expects to receive a $20 million  payment from
Intel in the third  quarter of fiscal 2004 and another $2.5  million  payment in
the fourth quarter.

For the third quarter of fiscal 2004, SMSC expects  revenues to be approximately
$70 million,  including the special $20 million payment. Excluding that payment,
revenues are expected to increase by  approximately  23%  year-over-year.  Gross
profit  percentage  is expected to be  approximately  60% in the third  quarter,
including the impact of the special payment,  or approximately  44% without that
impact.  Research  and  development  expenses  are  expected to be between  $9.5
million and $10.0 million, and selling,  general and administrative expenses are
expected to be between $10.5 million and $11.0 million. Amortization of acquired
intangibles is expected to be $317 thousand. The effective tax rate is estimated
to be  approximately  36% in the third  quarter,  and the Company  expects third
quarter  income from  continuing  operations  to be between  $0.75 and $0.80 per
share, including the special payment, and up slightly from the second quarter of
fiscal 2004 without that payment.

For fiscal 2004, SMSC expects revenues to increase by more than 35%, as compared
with fiscal 2003, including the $22.5 million of special payments,  or by 20% to
25% without those payments. This significantly exceeds previous guidance,  which
indicated a more than 15% revenue  increase  over the prior year.  Gross  profit
percentage,  including the special payments,  is expected to exceed 50%. Without
the impact of the payments,  gross profit is expected to be  approximately  45%.
Research and development expenses are expected to be between $37 million and $38
million,  and selling,  general and  administrative  expenses are expected to be
between $40 million and $41 million.  Amortization  of acquired  intangibles  is
expected to be  approximately  $1.3  million.  The effective tax rate for fiscal
2004 will be  approximately  35%. Income from  continuing  operations for fiscal
2004, including the $22.5 million of special payments, is expected to be between
$1.05 and $1.15 per share,  or  between  $0.30 and $0.35 per share  without  the
special payments, an increase of approximately 25% from prior Company estimates.
Prior Company guidance called for income from continuing operations to be in the
range of $0.24 to $0.28 per share.

Andrew M. Caggia,  Senior Vice President and Chief Financial  Officer said, "The
investments  we have made in new product  development  have enabled SMSC to gain
measurable  traction  in a wide range of emerging  markets.  As a result of this
success,  coupled with  increasing  revenues in  businesses we have long served,
SMSC is looking forward to its seventh sequential quarter of increasing revenues
and expects to continue to outperform the  industry's  growth during this fiscal
year."
