     SMSC REPORTS OVER 70% YEAR-OVER-YEAR INCREASE IN THIRD QUARTER REVENUES

                          Posts Strong Earnings Growth

Hauppauge,  NY - December 15, 2005 - SMSC (Nasdaq:  SMSC) revenues for the third
quarter ended November 30, 2005 rose by over 70% to $86.6  million,  compared to
last year's third quarter revenues of $50.8 million, and by 10% sequentially. On
a GAAP basis, operating income was $6.7 million in the third quarter compared to
an operating  loss of $0.4 million a year ago, and net income was $5.4  million,
or $0.24 per share,  compared to $0.6 million,  or $0.03 per share, in the third
quarter of last year.

To provide additional  insight into cash earnings  capacity,  SMSC also presents
results on a non-GAAP basis,  excluding non-cash acquisition related charges and
non-cash  charges  associated  with Stock  Appreciation  Rights (SARs).  On this
basis,  non-GAAP  adjusted  operating  income  was  $11.8  million,  or 13.6% of
revenues,  compared to an operating loss of $0.1 million in the year-ago period.
Non-GAAP adjusted net income was $8.6 million,  or $0.38 per share,  compared to
net income of $0.8 million, or $0.04 per share, in the third quarter last year.

A reconciliation  of GAAP to non-GAAP  measures is provided in the schedule that
accompanies this release which,  together with additional  disclosure in a slide
presentation   on  quarterly   highlights,   is  posted  on  SMSC's  website  at
www.smsc.com.  These materials will be discussed in a management  teleconference
scheduled for 5:00 PM Eastern  Standard  Time,  December 15, 2005.  Presentation
materials and a link to a webcast of the teleconference  will be accessible from
the investor relations section of the website.

Approximately 40% of the year-over-year  revenue growth was due to the inclusion
of OASIS SiliconSystems  Holding AG (acquired March 30, 2005), and approximately
60% of the  revenue  growth came from SMSC's  pre-existing  products.  Excluding
products  acquired  through  the OASIS  acquisition,  revenues  on a  comparable
year-over-year basis increased approximately 70% in the Consumer Electronics and
Infotainment markets, approximately 10% in the Industrial and Other markets, and
approximately 25% in the Mobile and Desktop PC markets.

Including the acquisition,  third quarter revenues from the Consumer Electronics
and Infotainment  markets  comprised  approximately  36% of total revenues,  and
revenues from the Industrial and Other markets  accounted for  approximately 17%
of the total. Revenues from Mobile PC were strong and outpaced revenues from the
Desktop PC  market,  which were flat  sequentially  and lower on a  year-to-year
comparative quarterly basis.  Together,  revenues from the Mobile and Desktop PC
markets generated 47% of third quarter revenues. Evidencing its continuing focus
on more  defensible  and  differentiated  products,  the Company  estimates that
approximately  80% of all units shipped  during the third quarter were analog or
mixed-signal products.

Steven J. Bilodeau,  Chairman and Chief Executive Officer, said "We believe SMSC
has now demonstrated its capacity for sustainable revenue,  operating income and
net income growth.  We have a balanced  business and expanding margins resulting
from the  investments  in new  products in prior  periods.  Our  intention is to
continue to create value by investing in new product development to drive future
growth, as well as in the infrastructure needed to support this planned growth."

Cash and liquid  investments at November 30, 2005 were $141.7 million,  compared
to $131.7  million at August 31,  2005.  The Company has no bank debt,  and book
value per share was $14.76 as of November 30, 2005.

For the fourth quarter, revenues are expected to be between $82 and $86 million,
representing  a 53%  increase  at the  midpoint  of  guidance  versus the fourth
quarter  revenues of the prior  fiscal  year.  Non-GAAP  adjusted  net income is
expected to be between $0.28 and $0.34 per share,  assuming  approximately  23.5
million diluted weighted average shares outstanding.  This guidance is presented
only on a non-GAAP basis because of SMSC's inability to project its future stock
price and any  resultant  adjustment  that might be  required  to adjust SARs to
market value.  It excludes  non-cash  acquisition  related  charges and all SARs
related  charges.  Please refer to the SMSC website at www.smsc.com  for further
details regarding fourth quarter guidance contained in the conference call slide
presentation.

Notes:
SMSC uses certain  non-GAAP  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
GAAP and non-GAAP results.

(a)  The  adjustment  to Cost of goods sold includes $65 to remove 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 only impacted GAAP
     Cost of goods sold for the  turnover  period of the OASIS  inventory at the
     date of acquisition, which was completed in September 2005.

     The remaining $154  adjustment to Cost of goods sold is to remove  non-cash
     charges associated with Stock Appreciation Rights (SARs). SMSC includes the
     actual cash cost of SARs in non-GAAP results as SARs are exercised.

(b)  The  adjustments  to  Research  &  development   and  Selling,   general  &
     administrative  expense  are to  remove  the  impact  of  non-cash  charges
     associated  with  SARs.  SMSC  includes  the  actual  cash  cost of SARs in
     non-GAAP results as SARs are exercised.

(c)  The adjustment to  Amortization  of intangible  assets for the three months
     ended November 30, 2005 includes  $1,282  related to the OASIS  acquisition
     and  $265  related  to the  fiscal  2003  acquisition  of  Gain  Technology
     Corporation  (Gain). The adjustment for the three months ended November 30,
     2004 relates entirely to the Gain acquisition.

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

Notes:

SMSC uses certain  non-GAAP  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
GAAP and non-GAAP results.

(a)  The  adjustment to Cost of goods sold includes  $1,652 to remove 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 only impacted
     GAAP Cost of goods sold for the turnover  period of the OASIS  inventory at
     the date of acquisition, which was completed in September 2005.

     The remaining $526  adjustment to Cost of goods sold is to remove  non-cash
     charges associated with Stock Appreciation Rights (SARs). SMSC includes the
     actual cash cost of SARs in non-GAAP results as SARs are exercised.

(b)  The  adjustments  to  Research  &  development   and  Selling,   general  &
     administrative  expense  are to  remove  the  impact  of  non-cash  charges
     associated  with  SARs.  SMSC  includes  the  actual  cash  cost of SARs in
     non-GAAP results as SARs are exercised.

(c)  The  adjustment to  Amortization  of intangible  assets for the nine months
     ended November 30, 2005 includes  $3,460  related to the OASIS  acquisition
     and  $797  related  to the  fiscal  2003  acquisition  of  Gain  Technology
     Corporation  (Gain).  The adjustment for the nine months ended November 30,
     2004 relates entirely to the Gain acquisition.

(d)  The adjustment to In-process  research and  development for the nine months
     ended November 30, 2005 removes a charge related to the OASIS acquisition.

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