Exhibit 99.1

                   SMSC REPORTS 30% YEAR-OVER-YEAR INCREASE IN
               FIRST QUARTER REVENUES, INCLUDING OASIS ACQUISITION

                 Earnings Per Share Exceeds Company Expectation

Hauppauge,  NY - June  29,  2005 - SMSC  (Nasdaq:  SMSC)  today  announced  that
revenues  for the first  quarter  ended  May 31,  2005 were  $68.8  million,  an
increase of  approximately  30% from last year's first quarter revenues of $53.1
million.  Of  the  30%  increase,  18%  was  due  to the  acquisition  of  OASIS
SiliconSystems  Holding AG (OASIS),  which closed on March 30, 2005, and 12% was
due to growth in SMSC's other products lines.  Gross profit percentage was 47.0%
for the three months ended May 31, 2005 and 50.3% for the year-earlier  quarter.
Operating  income for the period was $3.7  million,  compared to $3.6  million a
year ago.  Net income was $0.15 per share in first  quarter of fiscal year 2006,
compared to $0.15 per share in the first quarter of last year.

To provide  additional  insight  into its  underlying  operations,  SMSC is also
presenting a first  quarter  fiscal 2006  statement of operations on a pro forma
(non-GAAP) basis,  excluding  non-cash  acquisition-related  charges,  which are
in-process  research and development,  amortization of acquired  intangibles and
adjustments  to the  value  of  opening  inventory  at  the  date  of the  OASIS
acquisition.  This  statement is presented in a format that  reconciles  the pro
forma, non-GAAP measures to the most comparable GAAP measures.

On a pro forma basis, operating results were as follows. Gross profit percentage
for the  period  was  47.9%,  compared  to 50.3% in the  previous  year's  first
quarter,  exceeding  SMSC's  prior  expectation  due to a shift in mix to higher
margin products.  Operating income was $6.4 million, or 9.3% of sales,  compared
to $4.0 million,  or 7.5% of sales, in the year-ago period. Pro forma net income
was $4.7  million or $0.23 per share,  an increase in earnings per share of 44%,
from pro  forma  net  income  of $3.1  million,  or $0.16 per share in the first
quarter of fiscal 2005.

"Revenues for the first quarter were robust,  driven by the addition of revenues
from  OASIS  and  strong  sales  of our  mobile  PC,  EMC and  USB  connectivity
products," said Steven J. Bilodeau,  Chairman and Chief Executive  Officer.  "We
realized higher  profitability  than anticipated due to product mix coupled with
lower operating expenses than previously projected.  As sales increased, we also
benefited  from positive  leverage in our  operating  expenses,  which  improved
operating profit margins by nearly 4% of sales."

Mr.  Bilodeau  continued,  "This is an exciting  time for our business as we are
realizing  the  benefits  of  investments  made in recent  years to build a more
diversified  global  semiconductor  company.  This was also the first quarter of
sales  contribution  from our  recent  OASIS  acquisition,  which is now our new
Automotive  Infotainment  Systems group, and we are pleased with the progress of
the  integration of this business into SMSC.  These strong first quarter results
demonstrate  that our strategy to drive sales growth and improved  profitability
is on track."

Cash and liquid  investments  at May 31, 2005 were $121.0  million,  compared to
$172.6 million at February 28, 2005, of which approximately $61 million,  net of
cash acquired,  was utilized in the  acquisition of OASIS on March 30, 2005. The
Company  has no bank  debt,  and book  value per share was  $14.57 as of May 31,
2005.

Pro Forma Business Outlook:

Second  quarter  guidance  for pro forma net  income,  which is  expected  to be
between  $0.17 and $0.21  per  share,  is  presented  only on a pro forma  basis
because of SMSC's  inability to project its future stock price and its impact on
any expense provision that might be required to mark Stock  Appreciation  Rights
(SARs) to market until the end of the fiscal quarter.

For the second  quarter,  in line with the pro forma net income  guidance above,
SMSC expects the following measures on a pro forma basis:

o    Revenues  to  be  between  $73  million  and  $77  million,   reflecting  a
     year-over-year increase of nearly 50% at the midpoint of that range.
o    Gross profit percentage to be between 46% and 48%.
o    Research and development expense to be between $14 million and $15 million.
o    Selling,  general and administrative  expense to be between $15 million and
     $16 million.
o    The  effective  tax rate to be  approximately  36%,  including  an expected
     one-time  provision related to a streamlining of the legal entity structure
     of certain wholly owned subsidiaries acquired from OASIS.

Expense   recognition   related  to  SARs  is  determined  by  a  mark-to-market
calculation  based on the SMSC stock price at the end of each  period.  The SARs
outstanding as of May 31, 2005 have an average  exercise price of  approximately
$17.10.  Each $1.00  increase in SMSC's share price over $17.10 as of August 31,
2005 would  require an expense  provision of  approximately  $0.7 million  ($0.4
million  or  $0.02  per  share,  after  tax) in the  second  quarter,  based  on
approximately  1.5 million SARs  outstanding.  None of the SARs  outstanding are
currently  vested and all SARs are scheduled to vest between  September 2005 and
April 2010.

In addition,  the pro forma  adjustments  included in the guidance above exclude
the  impacts  of  two  non-cash  acquisition  related  charges,  which  are  the
amortization  of acquired  intangibles,  estimated  to be $1.6  million,  and an
adjustment  to the cost of goods  sold to  reflect  the  write up of the cost of
inventory  at the date of the OASIS  acquisition,  which is estimated to be $0.9
million.

Notes:
SMSC uses pro forma  information to evaluate its operating  results and believes
such  information  also  provides  investors  with  additional  insight into its
underlying operations.  This schedule presents a full reconciliation between pro
forma and GAAP results.

(a)  The  adjustment  to Cost of goods  sold is to  remove  from  the pro  forma
     results the impact of writing up the cost of  inventory  at the date of the
     Oasis acquisition over Oasis' original cost of the inventory. That write up
     will only  impact  GAAP Cost of goods sold for the  turnover  period of the
     OASIS  inventory  at the  date of  acquisition.  That  turnover  period  is
     expected to conclude in the quarter ending November 30, 2005.

(b)  The adjustment to In-process research and development is to remove from the
     pro forma results the cost of in-process  research and development that was
     purchased in the Oasis acquisition and immediately expensed.

(c)  The adjustment to  Amortization  of intangible  assets for the three months
     ended May 31, 2005 includes $887 related to the Oasis  acquisition and $266
     related to the  fiscal  2003  acquisition  of Gain  Technology  Corporation
     (Gain).  The  adjustment  for the three  months  ended May 31, 2004 relates
     entirely to the Gain acquisition.

(d)  The  adjustments  to the  Provision  for  income  taxes was  determined  by
     applying the appropriate incremental tax rates to the adjustments described
     in notes (a) through (c) above.
