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
