Lattice Field Programmable System-on-a-Chip Demonstrates 4G Fibre Channel Capability

ORT82G5 FPSC performs at over 4.25Gigabits/sec, provides support for emerging standard for next-generation storage systems

HILLSBORO, OR - DECEMBER 1, 2003 - Lattice Semiconductor Corporation (NASDAQ: LSCC) today announced that its ORT82G5 Field Programmable System-on-a-Chip (FPSC) has demonstrated the ability to pass error-free data at 4.25Gigabits/sec (Gbps) across 6 inches of printed circuit board (PCB) and 26 inches of coaxial cable, making it the industry's first programmable 4G Fibre Channel-based backplane transceiver in production. In June of this year, the Fibre Channel Industry Association (FCIA) voted in favor of extending 4Gbps Fibre Channel (4GFC) from an intra-cabinet storage device interconnect into switched Storage Area Network (SAN) fabrics. 4GFC serves as a bridge between the 10Gbps future and current 1-2Gbps systems.

"Lattice's superior SERDES technology, systems knowledge and programmable technology expertise continue to provide effective solutions for high performance applications like storage arrays and next-generation storage networks," said Stan Kopec, vice president of corporate marketing at Lattice. "The ORT82G5 is production-proven, and we have been working with leading-edge vendors in the SAN market to verify the 4GFC capability of the device. All our tests confirm the superior speed, flexibility, and low power consumption of our solution. Our customers are getting a real jump on the 4GFC market with a proven device ready for design and production now," he added.

Lattice's ORT82G5 includes 4 SERDES channels that run at over 4.3Gbps, an embedded Fibre Channel Physical Coding Sublayer (PCS) core with 8b/10b encoding/decoding and link state machine, and over 10,000 programmable logic elements (equivalent 4-input lookup tables) in its general-purpose FPGA section for the easy integration of customer-specific intellectual property (IP). The device also features 372 general-purpose programmable I/O pins supporting a variety of advanced interface standards including HSTL, SSTL, GTL+ and others. A low 335 milliwatts of power is consumed per channel with the SERDES running in excess of 4.25Gbps.

Lattice's FPSC devices are high-performance field programmable devices that combine optimized embedded core functions together with flexible, general-purpose FPGA logic. Lattice currently has 10 FPSC devices available, including devices optimized for SONET/SDH, Gigabit Ethernet, System Packet Interface (SPI) 4.2 and optical module interface applications. FPSCs offer system designers the convenience and time-to-market advantages of pre-engineered, pre-characterized standard interface functions combined with the flexibility of FPGA logic for the implementation of differentiated, application-specific features.

To document the 4GFC characteristics of its ORT82G5 SERDES technology, Lattice has also released an application note (Lattice Tech Note #1048) on its website at http://www.latticesemi.com, entitled "ORT82G5 4.25 Gbit/s Fibre Channel Testing Results".
