Lattice Semiconductor Joins the HyperTransport Consortium

Sunnyvale, Calif., September 6, 2007 - Further demonstrating broad momentum and adoption of HyperTransport( interconnect technology, the HyperTransport Technology Consortium today announced that Lattice Semiconductor Corporation (NASDAQ: LSCC), a leading supplier of programmable logic solutions, has joined the organization.

"HyperTransport technology is central to our strategy of ensuring that customers have the IP cores they need to rapidly deploy performance-leading systems in a variety of markets such as networking and computing," said Stan Kopec, Lattice's corporate vice president of marketing. "Our high-level membership in the Consortium enables us to influence the direction of the standard and to gain the advanced visibility on HyperTransport developments that will give us the ability to meet our customers' present and future performance objectives."

Boasting the industry's fastest implementation of HyperTransport technology in FPGA platforms to date, Lattice is offering the HyperTransport I/O as part of its Masked Array for Cost Optimization (MACO() structured ASIC technology, and has characterized the HyperTransport I/O link to operate at rates up to 1.6 Gbps. HyperTransport technology, combined with Lattice's own high-speed SERDES, high-performance fabric and industry-leading embedded ASIC technology, gives designers a powerful platform for satisfying their high-performance bridging and coprocessing needs.

"The addition of a leading FPGA supplier like Lattice demonstrates the on-going need for increased compute performance and throughput in fully scalable, application-specific computing systems and subsystems," said Mario Cavalli, general manager of the HyperTransport Consortium. "We welcome Lattice to the HyperTransport Consortium and look forward to leveraging their technology expertise and contribution to further enhance the HyperTransport standard."
