Lattice Devliers Industry's Fastest QDR II/II+ Memory Controller Support

LatticeSC and LatticeSCM FPGA Families Now Support QDRII/II+ Rates up to 750Mbps

HILLSBORO, OR -- DECEMBER 12, 2007 -- Lattice Semiconductor Corporation (NASDAQ: LSCC) today announced industry-leading FPGA-based support for Quad Data Rate (QDR) II/II+ memory devices. The LatticeSC( and LatticeSCM( FPGA families (collectively, the "LatticeSC/M" family) now support QDRII/II+ rates up to 750Mbps. The high-speed QDR II and QDR II+ memory controller IP (intellectual property) is implemented in Lattice's unique and low power Masked Array for Cost Optimization (MACO(tm)) structured ASIC technology.

"We are pleased to announce our partnership with Cypress Semiconductor Corporation," said Stan Kopec, Lattice corporate vice president of marketing. "Our high-speed support for QDR II/II+ memory controllers provides our customers with the industry's fastest programmable interface to Cypress' next generation QDR II/II+ memory devices. The LatticeSCM MACO memory controllers are a low risk, proven solution that delivers a higher level of performance than other FPGA solutions, while also reducing time to market for our users: another example of Lattice's 'More of the Best' philosophy."

"We are pleased to work with Lattice Semiconductor to support our next generation QDR II+ memory devices," said Bruce Barbara, SRAM marketing director for Cypress. "The Lattice memory controllers provide our customers with an excellent programmable platform to take advantage of our fastest QDR II+ devices."

The Quad Data Rate II+ memory devices are the latest members of the QDR SRAM memory family and allow data rates above 250 MHz. These new SRAMs are ideal for high-bandwidth, low latency applications. The read and write ports run independently and allow designers to maximize bandwidth without having to worry about the bus contention issues that are typical with other memory devices. The high bandwidth and low latency characteristics of the QDR II+ memories make them ideal for high-bandwidth applications in which they serve as the main memory for look-up tables, linked lists and controller buffer memory. These are used extensively in next generation switch and router platforms.

Lattice's unique MACO embedded structured ASIC blocks are available on LatticeSCM FPGA devices and deliver pre-engineered, standard-compliant IP functions developed by Lattice to shorten end-system time to market. Unlike the soft IP cores commonly used with FPGAs, the MACO IP functions are embedded into the devices, and there is no distinct IP license fee associated with their use. These enhanced memory controllers provide the industry's fastest programmable memory interfaces supporting next generation QDR II and QDR II+ memory devices, as well as DDR I/II and RLDRAM I/II memory devices. Lattice's ispLEVER( version 7.0 software design tool suite supports a complete HDL-based design and verification flow for LatticeSCM devices, as well as other Lattice leading-edge programmable device families.
