Fujitsu Microelectronics Develops New Complex, High-Pin-Count ASIC Series for Foundry Networks

Designed for use in foundry networks' switching and routing products

San Jose, CA, January 29, 2001 — Fujitsu Microelectronics, Inc. (FMI) and Foundry Networks, Inc. (NASDAQ-FDRY) today announced that FMI developed a set of complex ASICs for Foundry Networks' switching and routing solutions for enterprise and service-provider networks.

FMI is supplying several ASICs that feature very high pin counts in complex EBGA packaging for Foundry Networks' leading-edge family of high-performance, end-to-end switching and routing products.

Fujitsu's ASIC methodology uses a variety of 0.18 micron embedded array and standard cell process technology to produce a complex, highly integrated solution that meets the key on-chip and off-chip timing conditions required for rapid IP packet processing, explained Kaushik Banerjee, director of FMI's WAN/LAN business unit and U.S. design centers, who lead the development team.

"We are very pleased with Fujitsu's overall performance in the areas of design services and their approach to giving special attention to our engineering requirements and high priority to our market needs," said Richard Grenier, director of ASIC development, Foundry Networks. "Having a dependable ASIC supplier that can meet our silicon needs in 0.18 micron technology consistently with the senior management support on critical issues enables our time-to-market competitiveness."

"Our advanced design methodologies and packaging processes enable reliable development of complex ASIC products for the important high-end local area and wide area network market sectors," said Ryusuke Hoshikawa, president and chief executive officer of FMI. "These capabilities, housed in our design centers in San Jose, Dallas and Raleigh, provide our development partners with the industry's best tools and facilities for creating the products they need to meet their customers' time-to-market demands."

The relationship with Foundry Networks, which will continue as the companies work together on next-generation technology, is part of FMI's program to serve the rapidly expanding LAN/WAN sector, Hoshikawa added.
