             PERICOM SEMICONDUCTOR REPORTS Q1 2007 FINANCIAL RESULTS

                      REVENUES UP 37.2 PERCENT OVER Q1 2006

    SAN JOSE, Calif., Oct. 26 /PRNewswire-FirstCall/ -- Pericom Semiconductor
Corporation (Nasdaq: PSEM), a worldwide preferred supplier of PCI Express
technology used for switching, timing, connecting and signal integrity, today
announced results for its first quarter of fiscal 2007, ended Sept. 30, 2006.
Net revenues in the first quarter were $30.8 million, up 5.3 percent from
revenues in the fourth quarter and up 37.2 percent from the $22.5 million
reported in the comparable period last year. Net income in the quarter was $1.6
million, or $0.06 per diluted share compared with net income of $2.1 million, or
$0.08 per diluted share in the fourth quarter and versus net income of $0.6
million, or $0.02 per diluted share, in the same period a year ago.

    "We are very pleased with our revenue growth in Q1, which was driven by
increased shipments of our HDMI switch products into digital video applications,
and the ramp-up of our PCI Express products for notebooks, servers and graphics
applications. We also expanded our product solutions for serial differential
protocols and continued to see strong interest from our customers," said Alex
Hui, President and Chief Executive officer.

    Q1 NEW PRODUCTS

    Continuing to expand upon the PCISIG certified PCI-e Packet Switch and
Bridge offerings, Pericom announced Packet24(TM), a family of 4 new PCI Express
Packet Switches, ranging from 3 port-12 lanes to 4 ports-24 lanes
configurations. These new products provide customers with a higher performance
and feature-set to fit their needs; they further broaden Pericom's comprehensive
PCI Express offerings. Target applications for Packet24(TM) include high volume
blade and motherboard servers, HBA and NIC cards, networking, embedded and
storage applications.

    Enhancing Pericom's product positioning in high growth Digital Video
Platforms, the company has launched three new Spread-spectrum clock generators
(PI6C345x) and two VCXO's (PI6CX2xx) targeting DLP projectors, DLP TV, HDTV and
Digital Set-top box applications.

    The company also released two new LVPECL differential clocks (PI6C4853xx)
for Gigabit Ethernet networking switch clock distribution application. These new
products target high growth communication platforms where applications require
precise timing distribution.

    Fiscal Q2 2007 OUTLOOK

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

    * The company continues to be in a high turns environment and therefore
      revenue visibility remains limited. Depending upon the strength of turns
      orders, revenues are expected to be in the range of $30.8 million to $31.7
      million in the second quarter. Gross margins are expected to be in the 35
      percent to 37 percent range. Margins are influenced by the product mix of
      turns business and sales, if any, of previously written down inventory.

    * Operating expenses are expected to decrease to a range of $9.0 million to
      $9.3 million.

    * Other income is expected to be approximately $1.1 million, consisting
      primarily of interest income.

    * Equity in net income (loss) of investees is expected to be approximately
      $200,000.



    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
