Altera Ships Industry's Highest-Density FPGAs Qualified for Production

San Jose, Calif., December 27, 2004 — Altera Corporation (NASDAQ: ALTR) today announced that it is shipping the Stratix® II EP2S90 device, the industry’s largest and fastest FPGA qualified for production.

“Like the previous Stratix generation, nearly every aspect of the Stratix II family’s rollout has been exceptional,” said David Greenfield, senior director of product marketing for high-density FPGAs at Altera. “Stratix II devices are not only the fastest-ramped 90-nm FPGAs, but also the highest-density and highest-performance production-qualified FPGAs, delivering a 39 percent performance advantage on average over any other available FPGA.”

The EP2S90 device joins the EP2S30 device as the second member of the Stratix II FPGA family to be qualified for production, and the fourth member of the family overall to be shipping to customers.

The EP2S90 device has 90,960 equivalent logic elements (LEs) and more than 4.3 Mbits of embedded memory.

Availability

Today, Altera is shipping four Stratix II device family members. The EP2S60 and EP2S130 devices are available in engineering samples. The EP2S30 and EP2S90 devices are shipping in production. The entire Stratix II family will move to production status during the first half of 2005.
