Lattice To Showcase Award Winning 90NM FPGAs, Present Paper At The Embedded Systems Conference Silicon Valley

- New PCI Express Solutions, Open Source Embedded Microprocessor and Software Design Tools also Featured -

HILLSBORO, OR - MARCH 6, 2007 -- Lattice Semiconductor (NASDAQ: LSCC) today announced that it will demonstrate its award winning low-cost 90nm LatticeECP2M and LatticeSC Extreme Performance FPGAs at the Embedded Systems Conference Silicon Valley, San Jose Convention Center, April 3-5, in Booth 642. New mixed signal devices for clock and power management, particularly well suited for embedded applications, also will be featured, as well as the LatticeMico32 32-bit soft microprocessor and the Lattice ispLEVER( software design tool suite.
"Since last year's Embedded Systems Conference in Silicon Valley, Lattice has introduced a steady stream of new and innovative products, including our Product of the Year award winning LatticeECP2M FPGA family, the only low-cost devices to offer DSP blocks, embedded SERDES I/O and on-chip Embedded Block RAM of up to 5.3 Mbits," said Stan Kopec, corporate vice president of marketing. "The Embedded Systems Conference 2007 also will be the first opportunity for many attendees to see our LatticeMico32 embedded microprocessor, which is available at no charge through a unique Open Source license. Lattice also has introduced a vast array of new IP cores, including PCI Express solutions for our LatticeSC and LatticeECP2M FPGA families, and we've made significant enhancements to our ispLEVER design tool suite. The show will be a great opportunity for attendees to view demonstrations of our new products and to discuss their features, technologies and benefits with our technical applications personnel. At the ESC, Lattice will showcase what we believe to be the most comprehensive and technologically differentiated programmable logic products in the industry, including our unique non-volatile LatticeXP( and MachXO( devices, our new automotive grade, AEC-Q100 certified programmable logic product families and our FreedomChip( cost reduction path for the LatticeSC FPGA family. We have a very strong story to tell, and we are looking forward to sharing it with the attendees."

Lattice also announced that Gordon Hands, director of strategic marketing/Silicon Valley, will present his paper, "High-Performance Image Interfaces in Low-Cost Programmable Logic," which addresses the practical implementation in a low-cost FPGA of high-speed source-synchronous LVDS interfaces for transferring image data at speeds up to 595 Mbps. The presentation, designated ESC 327, will be Wednesday, April 4 from 11:00-12:30 in the Plaza meeting room of the Crown Plaza Hotel, which is directly across the street from the Convention Center.

About Lattice FPGAs and PLDs

The new 90nm LatticeECP2M FPGAs combine an efficient FPGA fabric with dedicated high-performance DSP blocks and SERDES I/O for high-volume, low-cost applications. The Extreme Performance 90nm LatticeSC FPGAs provide unsurpassed performance and connectivity for high-speed applications. LatticeXP non-volatile FPGAs combine SRAM and embedded Flash technologies to provide infinite reconfigurability and easy field upgrades. Lattice MachXO non-volatile crossover programmable logic devices support applications traditionally addressed by high density CPLDs or low capacity FPGAs, but with a more comprehensive and cost-effective architecture and technology.

About Lattice Mixed Signal Devices

The new Power Manager II devices replace power management functions typically requiring multiple ICs, including Reset Generators, Voltage Supervisors, Sequencers and Trackers. Lattice's ispClock( devices substantially reduce the clock network design effort, providing faster time to market, reduced board space and improved manufacturability and reliability.

About the LatticeMico32 Microprocessor

The LatticeMico32 microprocessor is a comprehensive, high performance and easy to use 32-bit processor solution. The LatticeMico32 microprocessor is unique among those offered by FPGA vendors in that the generated microprocessor and selected peripheral HDL code are licensed under Lattice's Open Source license agreement. This unique license allows users to ensure that their proprietary designs remain proprietary and allows the implementation and distribution of hardware without the need for a separate license agreement.
