GEORGE PERLEGOS RESPONDS TO MERITLESS LAWSUIT BY ATMEL

San Jose, Calif., March 23, 2007 – George Perlegos, a founder and the former President, Chief Executive Officer and Chairman of Atmel Corporation (Nasdaq: ATML), today issued the following statement in response to a lawsuit filed today by Atmel in the United States District Court for the Northern District of California:

“This meritless lawsuit is a waste of company resources and a desperate attempt by an entrenched board and management to distract investors from the recent poor performance of the company. My brother and I have complied – and will continue to comply – with all applicable provisions of the federal securities laws. I look forward to filing my preliminary proxy materials and to nominating five highly qualified and independent individuals who will work with urgency to reposition Atmel and hire a new CEO to revitalize the management team and build shareholder value.”

“As one of Atmel’s largest shareholders, I continue to be concerned by what I see as entrenching, self-enriching and value-eroding actions by the Board and this management team. Current management has overseen a deterioration in the company’s financial performance and has failed to make the fundamental changes I believe are necessary to improve the company’s results and position it for long-term growth.”

“The Delaware Chancery Court already has endorsed my right to call a special meeting and Atmel shareholders should have the right to vote on the future direction of their company. It is apparent to me that in filing this lawsuit, management and the board are placing their own self-interests above shareholders’ right to vote in an effort to protect their positions and defend Mr. Laub’s lucrative compensation package. I call on the Board and management to stop these distractions and engage in a meaningful dialogue on the future of the company.”

Mr. Perlegos led Atmel from its inception in 1984 until August 2006. Mr. Perlegos is seeking the removal of the following current directors of Atmel: Pierre Fougere, Dr. Chaiho Kim, Steven Laub, David Sugishita and T. Peter Thomas.

Latham & Watkins LLP and Potter Anderson & Corroon LLP are acting as legal counsel to Mr. Perlegos.

Atmel Corporation shareholders are strongly advised to read that proxy statement when it becomes available because it will contain important information.
