FOR IMMEDIATE RELEASE

XILINX FPGAS ABOARD MARS 2003 EXPLORATION MISSION

SAN JOSE, Calif., July 21, 2003 - Xilinx, Inc. (NASDAQ:XLNX), the world's leading programmable logic supplier, today announced that NASA's recently launched Mars Exploration Rover mission utilizes Xilinx FPGAs in critical applications for both the lander and rover vehicles. According to NASA's Jet Propulsion Laboratory in Pasadena, California, the Spirit Mars Exploration Rover (MER) launched June 10, 2003 and the Opportunity MER launched July 7, 2003 will employ some of the most advanced radiation tolerant Xilinx Virtex FPGAs once they reach Mars. The Xilinx devices will be used to control the pyrotechnic devices on the lander, and several motor control functions on the rover, including controllers for the wheels, steering, and antenna gimbals.

Chosen because of their re-programmability and density, the Virtex FPGAs serve as the 'main brain' of the motor control boards. "The MARS 2003 application of our advanced technology demonstrates the growing importance of Xilinx FPGAs to space exploration, " said Howard Bogrow, marketing manager for Aerospace and Defense products at Xilinx. "High performance radiation-tolerant reprogrammable FPGAs are serving more and more critical needs throughout the industry."

Xilinx currently supplies Virtex radiation tolerant products up to one million system gates and total ionizing dose guaranteed to 100 kRads(si). Soon to be announced is a family of Virtex-II products up to six million system gates and total ionizing dose guaranteed to 200 kRads(si).
