FOR IMMEDIATE RELEASE

XILINX DELIVERS VIRTEX-4 FPGAs

Company samples world's most advanced 90nm FPGAs to key customers

SAN JOSE, Calif., June 28, 2004 - Xilinx, Inc. (NASDAQ: XLNX), the world's leading supplier of programmable logic solutions and inventor of the FPGA, announced today that it has initiated shipment of Virtex-4 FPGAs to its early access customers. Manufactured using the world's first triple-oxide 90nm CMOS technology with 11-layer metal interconnect, Virtex-4 devices represent a quantum leap in programmable device architecture, technology, and system design capabilities. With over $2.5B in cumulative revenue, Virtex FPGAs are the world's most popular programmable logic brand.

The Virtex-4 FPGA family extends that leadership with a host of innovations that deliver unprecedented design capabilities to system designers worldwide.

• Triple-Oxide 90nm CMOS Process, enabling performance and system capacity increases of up to 2x compared to existing Virtex-II and Virtex-II Pro FPGAs.
  
  
• ASMBL architecture, a modular framework of silicon subsystems, enabling multiple platforms to most efficiently support different application domains.
  
  
• Advanced deep-submicron design techniques reducing dynamic and static power by half compared to previous generation Virtex FPGAs.
  
  
• 500MHz XtremeDSP™ Slices, delivering aggregate DSP performance of 256GigaMACs per second at record-setting power-efficiency levels of 56uW/MHz.
  
  
• 500MHz SmartRAM™, 18Kb configurable synchronous dual-port Static RAM, featuring integrated FIFO control logic to build fast FIFOs without consuming logic cell resources.
  
  
• 500MHz DCM™ Digital Clock Managers, offering sub-30ps timing resolution and the world's most advanced clock synthesis and timing capabilities.
  
  
• 500MHz high-performance on-chip differential clock networks for highest precision control of skew and duty-cycle.
  
  
• 0.6 - 11.1 Gbps RocketIO™ High-Speed Serial Transceivers, offering industry-leading bandwidth, and channel speeds including 10, 6.25, 3.125, 2.5, 1.25, and 0.6 Gbps.
  
  
• 32-bit RISC PowerPC™ processors delivering in excess of 1300 Dhrystone MIPS.

"We have been working with a select group of customers since the first of the year through our early access program. As a result, engineering teams are already designing next-generation products that simply were not possible before the introduction of our Virtex-4 FPGAs," said Erich Goetting, vice president and general manager of the Advanced Products Division at Xilinx.

About Xilinx Virtex-4 FPGAs
The initial Virtex-4 family includes three platforms; Virtex-4 LX optimized for logic-intensive designs, Virtex-4 SX optimized for very high performance signal processing and Virtex-4 FX for embedded processing and high-speed serial connectivity. Each platform will offer a range of device options. With up to 200,000 logic cells and up to 500 MHz performance, the Virtex-4 family delivers twice the density and up to twice the performance of any FPGA in the industry currently in production. Initial engineering samples of the Virtex-4 LX Platform FPGAs have already been delivered with general samples and additional platforms to follow shortly.
