     On March 1, 2000,  PMC-Sierra,  Inc. (the "Company") filed its Registration
Statement  on Form S-3  (File No.  333-31450),  covering  296,676  shares of the
Company's  Common Stock to be sold by certain  stockholders  of the Company.  On
March 31, 2000,  the  Securities  and Exchange  Commission  (the  ("Commission")
declared the Registration Statement effective.

     The  Registration  Statement  was filed in order to register  shares of the
Company's Common Stock issued to the former  stockholders of Toucan  Technology,
Inc. ("Toucan"), which was acquired by the Company on January 27, 2000.

     Pursuant  to Rule 477  promulgated  under the  Securities  Act of 1933,  as
amended,  the Company  respectfully  requests that the  Commission  withdraw the
Company's  Registration  Statement  on Form S-3. The Company is  requesting  the
withdrawal of the Registration  Statement because,  pursuant to the terms of the
Declaration of Registration  Rights under the Acquisition  Agreement between the
Company and Toucan,  the Company's  obligations to maintain the effectiveness of
the Registration Statement expired on January 27, 2001.

     Accordingly,  the  Company  hereby  de-registers  the 74,953  shares of its
Common Stock registered pursuant to the Registration  Statement remaining unsold
thereunder.
