Xilinx Press Release #0274

FOR IMMEDIATE RELEASE 

SAN JOSE, Calif., May 13, 2002-Xilinx, Inc., (NASDAQ:XLNX) and UMC (NYSE: UMC) today announced that the Xilinx Virtex^TM FPGAs series, which is almost entirely built in UMC's fabs, has reached one billion dollars in cumulative revenue since its introduction to the market in 1998. The milestone marks the first product series from a programmable logic company to reach the billion-dollar mark in less than five years. The most advanced products within this series, the Virtex-II^TM FPGAs, are built at UMC's 300mm Fab 12A on the company's 130 nm (0.13 micron) eight layer copper/low-k process.

Rich Sevcik, senior vice president of FPGA products at Xilinx said, "We are extremely pleased with the excellent die yields and competitive cost structure that UMC continues to deliver. On top of that, UMC's ability to meet our increasing volume requirements as demand for our products rises is an essential part of our success. We are looking forward to working with UMC on future developments particularly as we migrate to smaller process generations such as 90 nanometer and beyond."

"Xilinx is an excellent technology partner for UMC, as well as a winning customer," said Fu Tai Liou, chief officer of worldwide marketing and sales at UMC. Due to the FPGA vendor's high-volume requirements, we have migrated a large percentage of the company's production to 300 mm wafers. As the Virtex series chips feature larger die-sizes, Xilinx is able to realize the maximum cost benefits of manufacturing products on the larger wafers. We are pleased our efforts helped Xilinx reach this important milestone."

About the Virtex series
The Virtex FPGA product line currently includes four device families derived from the original Virtex family: the Virtex-E family, the award-winning Virtex-II Platform FPGA family, the Virtex-II EasyPathTM FPGAs, and the Virtex-II ProTM family of Platform FPGAs. This progression solves a wide variety of today's high-performance, robust feature set applications, such as optical networks, gigabit routers, wireless cellular base stations, modem arrays, and video broadcast systems. Capable of handling designs from 40,000 up to eight million system gates, the Virtex-II series features the highest performance, widest density range, highest density, and block RAM of any programmable solution available, with features Digital Clock Management (DCM) and XCITETM technology for improved signal integrity. The Virtex-II Pro family immerses as many as four IBM PowerPC processor cores and up to sixteen 3.125 Gbps Rocket I/O transceivers into the Virtex-II FPGA fabric. The Xilinx Integrated Solutions Environment (ISE) offers the most complete software environment for FPGA development and, to support the PowerPC immersion, Xilinx and Wind River Systems have the most complete embedded tools solution to design in the Virtex-II Pro FPGAs. Designers can now take advantage of pre-engineered solutions for embedded, DSP, and connectivity applications with 200 different cores that support the Virtex-II and Virtex-II Pro series.
