         PERICOM SEMICONDUCTOR REPORTS FISCAL 2006 FIRST QUARTER RESULTS

San Jose, CA - November 7, 2005 - Pericom Semiconductor Corporation [NASDAQ
National Market: PSEM] today announced results for its fiscal 2006 first quarter
ended October 1, 2005. Results for the previous quarter ended July 2, 2005 are
based upon 14 weeks versus a normal 13 week quarter which is the basis for this
quarters results. Results also include eCERA ComTek Corporation from the
September 7, 2005 acquisition date through October 1, 2005.

Net revenues for the first quarter were $22,473,000, up 6.4% from $21,121,000 in
the preceding quarter and up 13.6% from $19,786,000 in the comparable period
last year. GAAP net income for the quarter was $625,000, or $0.02 per share
(diluted), compared to GAAP net income of $1,173,000, or $0.04 per share
(diluted), in the preceding quarter and versus GAAP net income of $29,000, or
$0.00 per share (diluted), in the comparable period a year ago. During the
quarter ended October 1, 2005 the Company implemented Financial Accounting
Standard 123R (FAS123R), "Share-based Payment", which requires companies to
estimate the cost of all forms of stock based compensation, including stock
options, restricted stock and employee stock purchase plans, and recording of
this estimated compensation in the income statement. Implementation of FAS123R
is required for fiscal years commencing after June 15, 2005, therefore the
Company is one of the first to implement FAS123R. These expenses will be normal
going forward. Since this is the first quarter including these expenses, for
information purposes following are the amounts included in our GAAP and non-GAAP
results for the quarter ended October 1, 2005:

       Cost of Sales                                            $    24,000

       Total stock-based compensation                           $   278,000



NEWS RELEASE, NOVEMBER 7, 2005

Our GAAP financial results include unusual charges or events which are explained
in the reconciliation of non-GAAP and GAAP financial results that appears in the
financial statements portion of this release. Non-GAAP results are not meant as
a substitute for GAAP, but are included solely for informational and comparative
purposes. Pericom management believes non-GAAP financial information is useful
to investors because it illuminates underlying operational trends by excluding
significant unusual transactions. Our criteria for determining non-GAAP results
may differ from other companies' methods, and should not be regarded as a
replacement for corresponding GAAP measures.

Non-GAAP net income for the quarter ended October 1, 2005, including the FAS123R
expenses noted above, was $768,000, or $0.03 per share (diluted), compared to
$1,173,000, or $0.04 per share (diluted), in the preceding quarter and non-GAAP
net income of $29,000, or $0.00 per share (diluted), in the comparable period a
year ago which does not include any expense related to FAS123R.

Alex Hui, President and Chief Executive Officer of Pericom said, "In our first
quarter we delivered sequential revenue growth on our core IC and FCP lines of
4.3% (normalizing the preceding quarter to 13 weeks), and achieved our sixth
consecutive quarter of non-GAAP profitability. Additionally, our acquisition of
eCERA ComTek on September 7, 2005 provides a growing and accretive subsidiary
that further strengthens and broadens our FCP line with vertical integration,
captive low-cost manufacturing and local presence in the Taiwanese and Asian
markets. We are also pleased with the increasing acceptance of our PCI-Express
products for IT applications and our HDMI switching solution in digital video
applications. We expect these products will contribute significant revenue over
time."

NEWS RELEASE, NOVEMBER 7, 2005

DECEMBER 2005 QUARTER OUTLOOK

The following statements are based on current expectations. These statements are
forward looking, and actual results may differ materially.

     o    Including the full-quarter addition of eCERA, we expect a sequential
          increase in revenues of 18-20%. For the pre-eCERA IC and FCP business
          we are still reliant on a high level of turns business and expect
          revenues to be flat, plus or minus 2%.
     o    With the addition of eCERA, we expect consolidated non-GAAP gross
          margin to be approximately 33%, plus or minus 2%. GAAP margin will be
          slightly lower due to amortization of the eCERA inventory write-up to
          Fair Market Value required by acquisition accounting rules.
     o    Operating expenses, including eCERA and FAS123R expenses, are expected
          to increase to approximately $8.9 million, plus or minus $200,000.
     o    Other income, net, is expected to be approximately $1.0 million.
     o    Income from unconsolidated subsidiaries is expected to be zero to
          $200,000.
     o    Current expectation is that our tax rate will approximate 33%.

Pericom will adhere to Regulation Fair Disclosure. The Company will provide its
investors and analysts with guidance in the areas of total revenues, gross
margin, operating expenses and other income each quarter in our earnings
releases and in our conference calls. We will not provide further guidance or
updates during the quarter unless we do so via a press release.
