PRESS RELEASE

ATMEL REPORTS SECOND QUARTER 2001 FINANCIAL RESULTS

COMPANY TO IMPLEMENT AGGRESSIVE COST REDUCTION PROGRAM

         SAN JOSE, Calif.--(BUSINESS WIRE)--July 19, 2001--Atmel Corporation
(Nasdaq:ATML - news) today announced financial results for the second quarter
ended June 30, 2001. Revenues for the second quarter of 2001 totaled
$366,996,000, down 23% from a year ago, and down 30% sequentially. Net income
for the second quarter of 2001 was approximately breakeven, totaling a net loss
of $31,000, or $0.00 per share. In the previous quarter, the Company reported
net income of $56,014,000 or $0.12 per share. In last year's second quarter, the
Company's net income was $61,325,000 or $0.13 per share.

         George Perlegos, Atmel's President and Chief Executive Officer, stated,
"Business conditions at the end of the past quarter were very difficult. As we
indicated in our previous guidance, sales were impacted by continued weakness in
the Flash market, the European Smart Card business, and our North American
distribution business. During the quarter we implemented several cost reduction
measures, and intend to continue our strong focus on maintaining tight expense
control. Atmel is fully committed to remaining profitable. We will not hesitate
to take the necessary cost reduction actions to align our costs with the market
environment."

         Perlegos concluded, "As we look ahead, we are accelerating our strategy
of investing in new technologies and products. We believe this will be the key
to success in the next cycle. Based on information available to us today, we
believe that our business should bottom out in the third quarter, with a return
to growth thereafter."
