KNOW ALL MEN BY THESE PRESENTS, That the undersigned officer and/or director of
Microchip Technology Incorporated, a Delaware corporation (the "Company"), does
hereby constitute and appoint STEVE SANGHI AND C. PHILIP CHAPMAN, and each of
them, with full power to each of them to act alone, as the true and lawful
attorneys and agents of the undersigned, with full power of substitution and
resubstitution to each of said attorneys to execute, file or deliver any and all
instruments and to do any and all acts and things which said attorneys and
agents, or any of them, deem advisable to enable the Company to comply with the
Securities Exchange Act of 1934, as amended, and any requirements of the
Securities and Exchange Commission in respect thereto relating to annual reports
on Form 10-K, including specifically, but without limitation of the general
authority hereby granted, the power and authority to sign such person's name
individually and on behalf of the Company as an officer and/or director (as

the Company, to any Form 10-K.

IN WITNESS WHEREOF, each of the undersigned has subscribed these
presents this 30th day of January, 1998.
