Hitachi Expands SOC Capabilities with inSilicon's Hi-Speed USB 2.0 PHY

Certified Mixed-Signal Technology Accelerates Next-Generation Chip Performance

SAN JOSE, Calif.--(BUSINESS WIRE)--Aug. 5, 2002--inSilicon Corporation (Nasdaq:INSN - News) -- a leading provider of connectivity intellectual property (IP) technology for complex systems-on-chip (SOC) -- today announced that Hitachi, Ltd., located in Japan, has licensed inSilicon's USB 2.0 PHY with USB 2.0 Transceiver Macrocell Interface (UTMI) for Hitachi's SOC development.

Hitachi develops SOC solutions for digital imaging applications such as printers, scanners, and digital cameras. Under the terms of the agreement, Hitachi will integrate inSilicon's certified USB 2 PHY in their embedded H8S and SH processor-based SOC designs to provide cost-effective, high-speed USB solutions for the LSI semiconductor market. Compared to USB 1.1, the new high-speed USB 2.0 standard accelerates performance 40 times faster.

inSilicon's USB 2 PHY is the world's first semiconductor IP to pass Hi-Speed USB 2.0 compliance testing -- a key achievement in ensuring functionality and interoperability in next-generation USB 2.0 PC and consumer products. The PHY is a complete mixed-signal semiconductor IP solution designed for single-chip USB 2.0 integration in both device and host applications. The USB 2 PHY integrates high-speed, mixed-signal, custom CMOS circuitry compliant with the industry-standard UTMI specification. USB 2 PHY technology supports the USB 2.0 480 Mbps protocol and data rate, and is backward compatible with the USB 1.1 legacy protocol at 1.5 and 12 Mbps.

"Consumer products with USB 2.0 functionality will increase dramatically in 2003. inSilicon's stellar track record for USB semiconductor IP, combined with their technical expertise and support, ensures successful connectivity for our SOCs," said Hiroyuki Koizumi, manager, IP & CPU core development department, semiconductor & integrated circuits, of Hitachi, Ltd. "Licensing this sophisticated technology enables us to focus engineering resources on our core SOC designs and gives us significant time-to-market advantages over our competitors."

"Hitachi offers world-class, application-specific SOC solutions," said Xerxes Wania, vice president of mixed-signal business at inSilicon. "Providing our USB 2.0 digital and mixed-signal technology to Hitachi's customers ensures a solution that has been designed and tested for optimal implementation and reuse. Our product delivers USB 2.0 PHY performance and ensures interoperability for their designs."
