Lattice Semiconductor, Eureka Technology Announce Intellectual Property Support for new FPGA Families

IP Cores Run Significantly Faster On New FPGAs

HILLSBORO, OR / LOS ALTOS, CA - July 26, 2004 - Lattice Semiconductor Corporation (NASDAQ: LSCC) and its IP partner, Eureka Technology, Inc., today announced intellectual property (IP) support for the new LatticeECP-DSP^TM ("EConomyPlusDSP") and LatticeEC^TM ("EConomy") FPGA device families. Through the ispLeverCORE^TM Connection program, Lattice and Eureka Technology will provide a range of complete system solutions for their mutual customers who are integrating system-level IP with the most advanced silicon architectures. The Lattice partners program is designed to allow customers to easily access and integrate approved third-party IP products using Lattice programmable devices.

"Lattice is pleased to continue our partnership with Eureka Technology, a company that specializes in system core logic and peripherals and has an impressive history of successful customer engagements. We're very excited by the increased IP core performance that Eureka Technology has achieved using our new ispLEVER® software," said Stan Kopec, Lattice vice president of corporate marketing.

Simon Lau, President of Eureka Technology, Inc. said, "We are very happy with the new Lattice FPGA devices and the software tools used to implement designs to them. The new LatticeECP^TM and LatticeEC devices are much faster than previous FPGAs. Also, the new version of the Lattice ispLEVER software is very easy to use: compilation is straightforward and provides excellent results for our reusable IP products."

About the LatticeECP-DSP and LatticeEC FPGA Families
Introduced June 28, 2004, the LatticeECP-DSP and LatticeEC FPGA device families are architected to provide the most optimized feature sets combined with the lowest total solution costs of any FPGAs. The new LatticeECP-DSP products, targeted for high-performance DSP applications, provide up to a 50% performance and 75% logic utilization improvement over other low-cost solutions when implementing common DSP functions. The LatticeEC FPGA product family, targeted for general-purpose FPGA applications, is a precise and targeted response to the market's explosive demand for low-cost, architecturally streamlined logic solutions. Through advanced 130nm silicon technology, an optimized architecture and proprietary circuit design, the new Lattice devices lower total solution costs by up to 30% to 50% compared with existing FPGA solutions, and are expected to broaden the adoption of FPGAs within the $20 billion ASIC marketplace.
