Lattice Announces Production Release of 90nm LatticeECP2 Family

First Low-Cost FPGAs To Support  533Mbps DDR2 Memory Interfaces Now Shipping

HILLSBORO, OR – March 12, 2007 - Lattice Semiconductor Corporation (NASDAQ: LSCC) today announced that its LatticeECP2™-50 and Lattice ECP2-12 FPGA devices have been fully qualified and released to volume production. The second-generation LatticeECP2 “EConomy Plus” Field Programmable Gate Array (FPGA) families have been produced on 90nm Fujitsu CMOS technology utilizing 300mm wafers. Final characterization also confirmed the operation of the devices’ Double Data Rate 2 (DDR2) Synchronous Dynamic Random Access Memory (SDRAM) memory interfaces at 533Mbps, the industry’s fastest rate in a low-cost FPGA.

“The overriding objective for our LatticeECP2 products has been to combine high performance with low cost,” said Stan Kopec, corporate vice president of marketing. “It is especially exciting to deliver 533Mbps DDR2 performance in our Low-Cost FPGAs as they are production released, a capability two speed grades ahead of competitive low-cost devices. Where memory interfaces are concerned, our ‘More of the Best’ advantage couldn’t be more clear.”

Cost Optimized Architecture Provides Rich Feature Set

The LatticeECP2 devices have been optimized to deliver the features and cost structure required by designers for high-volume system applications, including an optimized logic and routing fabric; pre-engineered 840Mbps parallel I/O; pre-engineered DDR2 (now up to 533Mbps) memory interfaces; and full feature sysDSP™ Blocks. The overall family consists of a total of 6 logic densities, ranging from 6K to 70K LUTs available in 6 popular package configurations. The LatticeECP2 Family also provides other value-added features that are either not available in competitive FPGAs, or require the customer to use higher cost devices, including dual-boot and Transparent Field Reconfiguration (TransFR™) I/O support for easy field logic updates, as well as bit stream encryption with on-chip non-volatile key storage for enhanced design security.

Design Tools and IP Support

Design support for the LatticeECP2 devices is provided by the latest version of the ispLEVER® tool suite, Version 6.1 using Service Pack 2. The ispLEVER tools provide designers with access, in one software package, to all Lattice digital devices and include synthesis and simulation support from Mentor Graphics and Synplicity at no additional charge.

An extensive range of IP (Intellectual Property) cores, particularly suited for high volume applications, is available for these devices from both Lattice and its IP partners. Additional details are available on the Lattice website, www.latticesemi.com

Pricing and Availability

The LatticeECP2-50 and LatticeECP2-12 devices are available now in commercial and industrial temperature range options. The entire LatticeECP2 FPGA family is expected to be production released over the next quarter. These devices are available in several low-cost packaging options supporting pin-compatible footprints throughout the family for easy density migration. Pricing in 100,000 piece quantities for the LatticeECP2-50 for delivery in 2H 2007 starts at $21.00. The Memory Controller Intellectual property (IP) core for 533Mbps DDR2 is available immediately. Please see the separate Lattice press release, also released today.
