Lattice Semiconductor and Dune Networks Announce Collaboration To Develop SPAUI-Based Network Solutions

LatticeSC FPGAs To Provide Low Cost, Low Power SPAUI to SPI4.2 Bridging Solutions for Dune Networks’ FAPs and Traffic Managers

HILLSBORO, OR & SUNNYVALE, CA - OCTOBER 29, 2007 - Lattice Semiconductor, a leading FPGA provider, and Dune Networks, a provider of networking devices for Data Center, Enterprise and Carrier Ethernet scalable switching platforms, today announced they will collaborate in the development and marketing of SPAUI-based networking solutions.

LatticeSCM™ FPGAs provide an optimized programmable platform to bridge to switch fabrics and traffic managers by utilizing hardened Ethernet and SPI4.2 blocks implemented via exclusive Masked Array for Cost Optimization (MACO™) technology. Dune Networks’ FAP traffic managers provide ingress and egress programmable traffic management solutions that address the requirements of the MEF, IETF DiffServ, and DSL Forum TR-059/TR-101.

SPAUI is a serial interface based on the10GbE XAUI and SPI4.2 standards. By combining the benefits of both into one comprehensive standard, SPAUI enables system designers to take advantage of the ubiquity of XAUI as a physical layer as well as the multi-channel QoS and flow control mechanisms of SPI4.2. SPAUI is also designed to support aggregate rates of higher speeds. SPAUI is one of the interface options of Dune Networks’ SAND chipset.

“Dune Networks welcomes Lattice to the SPAUI ecosystem. The LatticeSCM device’s embedded MACO cores, especially the SPI4.2 core, offer our customers a low cost and low power programmable fabric interface chip option,” said Ofer Iny, CTO of Dune Networks. “By combining Dune’s industry leading SAND chipset with the LatticeSCM FPGA, we can provide a mutually beneficial solution to our customers at the lowest possible cost and footprint.”

“As demonstrated by our previously announced XAUI to SPI4.2 bridging solution, our LatticeSC™ and LatticeSCM FPGA devices are the ideal programmable platforms for Carrier Ethernet applications. We are very pleased to announce our cooperation with Dune Networks to provide a complete end to end packet fabric solution,” said Stan Kopec, Lattice corporate vice president of marketing.

When implemented in a LatticeSCM-15E FPGA in a space-saving 256 fine pitch Ball Grid Array (fpBGA) package, the Lattice XAUI to SPI4.2 bridging solution requires a mere 17mm x 17mm on a printed circuit board while consuming only 2.5Watts of power, substantially less than competitive devices.

About SPAUI

SPAUI, an interface based on the XAUI industry standard, incorporates several extensions that provide 10Gbps applications with speedup (for packet headers, full rate 12GE), channelization, packet interleaving and refined flow control. SPAUI is implementation-friendly, backward compatible to standard XAUI and ideal for dense 10GE and higher speed Ethernet solutions. The SPAUI memorandum is available upon request from Dune Networks at no cost.
