Exhibit 99.1

            SMSC REPORTS FOURTH QUARTER AND FISCAL YEAR 2006 RESULTS

   Fiscal 2006 Revenues Increase by 53% to $319 Million and EPS Grows by $0.47

Hauppauge,  NY - April 18, 2006 - SMSC  (Nasdaq:  SMSC)  revenues for the fourth
quarter ended February 28, 2006 rose by $29.7 million, or 54%, to $84.6 million,
compared to last year's fourth quarter revenues of $54.9 million,  and were down
by $2.0 million,  or 2%, from the third quarter of fiscal 2006,  consistent with
previous guidance and expected seasonality. Approximately $13.6 million, or 46%,
of the year-over-year  fourth quarter revenue growth was due to the inclusion of
OASIS  SiliconSystems  (OASIS),  acquired on March 30, 2005,  and  approximately
$16.1  million,  or 54%,  of the revenue  growth  came from SMSC's  pre-existing
product lines.

On a GAAP  basis,  operating  income was $3.3  million  in the  fourth  quarter,
compared to an  operating  loss of $6.9  million a year ago,  and net income was
$3.8 million,  or $0.16 per share,  compared to a net loss of $2.8  million,  or
$0.15 per share, in the fourth quarter of last year.

SMSC also presents results on an adjusted  non-GAAP basis to provide  additional
insight into underlying operating  performance on a comparable basis. For fiscal
2005,  this excludes a patent  litigation  settlement  and a gain on the sale of
real estate, and for fiscal 2005 and 2006, excludes non-cash acquisition related
charges and  non-cash  charges and credits  associated  with Stock  Appreciation
Rights (SARs). A reconciliation  of GAAP to non-GAAP measures is provided in the
schedule that accompanies this release.

On this basis,  non-GAAP  operating income for the fourth quarter of fiscal 2006
was $7.2 million, or 8.5% of revenues, compared to a loss of $2.4 million in the
year-ago  period.  Non-GAAP  net  income was $6.3  million,  or $0.27 per share,
compared  to net  income of $0.1  million  in the  fourth  quarter of last year.
Non-GAAP  net  income of $0.27 per share in the fourth  quarter  of fiscal  2006
includes a $1.1 million  expense ($0.7 million,  or $0.03 per share,  after tax)
for the cash impact of SARs that were exercised during the period. SMSC does not
consider  SAR-related expenses in its earnings estimates due to the inability to
predict  stock  prices and their  impact on SAR  exercises  during the  quarter.
Excluding these expenses,  non-GAAP  earnings per share were consistent with the
Company's prior estimates.

For fiscal 2006, SMSC posted record annual semiconductor product sales of $308.3
million,  56% higher  than  product  sales of $197.8  million in the prior year.
Total revenues  increased to $319.1 million from $208.8 million last year. OASIS
accounted  for $52.8  million of total  product  sales in fiscal 2006. On a GAAP
basis, net income per share was $0.55 versus $0.08 in fiscal 2005. On a non-GAAP
basis, as described above, net income per share was $1.13 versus $0.29 in fiscal
2005.

Cash and liquid  investments  at February 28, 2006  increased to $155.0  million
from $141.7 million at November 30, 2005. The Company has no bank debt, and book
value per share as of February  28, 2006 was $15.18.  SMSC's  February  28, 2006
Consolidated   Balance  Sheet  reports  a  $17.8   million   liability,   and  a
corresponding  increase in goodwill,  reflecting additional cash and SMSC common
stock  which is payable to former  OASIS  shareholders  in the first  quarter of
fiscal 2007, as a result of achievement of certain performance goals.

Steven J. Bilodeau, Chairman and Chief Executive Officer, said, "In fiscal 2006,
SMSC's revenues grew by over 54% from the prior year with more than half of that
growth coming organically.  Excluding the acquisition of OASIS, the Company grew
28%, or more than three times the rate of the semiconductor industry as a whole.
The  acquisition of OASIS and its Automotive  Infotainment  product line,  which
provided the balance of the revenue increase,  is proving to be an excellent fit
because  of its strong  growth  prospects,  as well as market and  technological
synergies.

"SMSC  significantly  improved  profitability as non-GAAP  operating income on a
full year basis reached  10.4% of revenues and non-GAAP  earnings per share rose
by $0.84 to $1.13.  Our current  product  portfolio and new product  pipeline is
giving us exciting new opportunities in all of our markets."

For the first  quarter of fiscal  2007,  revenues are expected to be between $82
and  $85  million,  which  represents  over  20%  year-over-year  growth  at the
midpoint.  Non-GAAP  net income is  expected  to be between  $0.23 and $0.27 per
share,  assuming  approximately  23.1 million  diluted  weighted  average shares
outstanding.  This  guidance is  presented  only on a non-GAAP  basis to provide
comparability to historical  non-GAAP  financial  measures and because of SMSC's
inability  to project its future  stock  price and the  charges or credits  that
might be required to record stock-based compensation. Accordingly, this guidance
excludes both non-cash  acquisition  related charges and the impact of expensing
stock-based  compensation in accordance with the  requirements of FASB Statement
No. 123(R),  which will be  effective  for SMSC  in the first  quarter of fiscal
2007.

A management  teleconference  to discuss the  quarterly and full year results is
scheduled  for  5:00  PM EDT,  April  18,  2006.  Slide  presentation  materials
containing   additional   disclosure   regarding  results  and  future  earnings
expectations,  and a link to a webcast of the teleconference  will be accessible
from the investor relations section of SMSC's website at www.smsc.com.

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 operating measures.

(a)  The  adjustment  to Cost of goods sold for the three months ended  February
     28,  2006  removes  the impact of non-cash  charges  associated  with Stock
     Appreciation  Rights  (SARs).  The  adjustment  for the three  months ended
     February 28, 2005 removes a $50 credit associated with SARs.

     As SARs are  exercised,  the actual  cash cost of SARs is  included  within
     non-GAAP operating measures.

(b)  The  adjustments  to  Research  &  development   and  Selling,   general  &
     administrative  expense  remove the impact of  non-cash  charges or credits
     associated with SARs.

     As SARs are  exercised,  the actual  cash cost of SARs is  included  within
     non-GAAP operating measures.

(c)  The adjustment to  Amortization  of intangible  assets for the three months
     ended February 28, 2006 includes  $1,279  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 February 28,
     2005 relates entirely to the Gain acquisition.

(d)  The adjustment to Settlement charge for the three months ended February
       28, 2005 removes the impact of a litigation settlement payment.

(e)  The  adjustment to Gains on real estate  transactions  for the three months
     ended  February  28,  2005  removes a gain  realized on the sale of an idle
     facility.

(f)  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 (e) 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 operating measures.

(a)  The adjustment to Cost of goods sold for the fiscal year ended February 28,
     2006  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 $630  adjustment to Cost of
     goods sold removes  non-cash  charges  associated  with Stock  Appreciation
     Rights  (SARs).  The adjustment for the fiscal year ended February 28, 2005
     removes a charge of $8 associated with SARs.

     As SARs are  exercised,  the actual  cash cost of SARs is  included  within
     non-GAAP operating measures.

(b)  The  adjustments  to  Research  &  development   and  Selling,   general  &
     administrative  expenses remove the impact of non-cash  charges  associated
     with SARs.

     As SARs are  exercised,  the actual  cash cost of SARs is  included  within
     non-GAAP operating measures.

(c)  The  adjustment to  Amortization  of intangible  assets for the fiscal year
     ended February 28, 2006 includes  $4,740  related to the OASIS  acquisition
     and $1,062  related  to the  fiscal  2003  acquisition  of Gain  Technology
     Corporation  (Gain).  The adjustment for the fiscal year ended February 28,
     2005 relates entirely to the Gain acquisition.

(d)  The adjustment to In-process  research and  development for the fiscal year
     ended February 28, 2006 removes a charge related to the OASIS acquisition.

(e)  The adjustment to Settlement  charge for the fiscal year ended February 28,
     2005 removes the impact of a litigation settlement payment.

(f)  The  adjustment  to Gains on real estate  transactions  for the fiscal year
     ended  February  28,  2005  removes a gain  realized on the sale of an idle
     facility.

(g)  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 (f) above.
