Seiko Instruments Selects Infineon's UMTS RF Transceiver for HSDPA High-Speed Data Communication Cards

Neubiberg, Germany – July, 17, 2007 – Infineon Technologies AG (FSE/NYSE: IFX) a leading provider of communication ICs today announced that Seiko Instruments Inc (SII) selected the SMARTi® 3G single-chip CMOS radio frequency (RF) transceiver developed by Infineon, for UMTS/HSDPA data card applications. SII, the leading vendor of RF data communication cards in Japan, will use the SMARTi 3G transceiver in its C01SI UMTS /HSDPA data card model to enable laptop and PDA users to connect to the Internet via the cellular network and enjoy download speeds of up to 3.6Mbp/s.

The new data communication card powered by the SMARTi 3G will be supplied to “Softbank Mobile” , a leading 3G mobile phone carrier in Japan, for use in Softbank Mobile's first data card UMTS/HSDPA service offering.

"The SMARTi 3G is a compact and highly advanced UMTS transceiver with proven quality and capabilities," said Takaaki Yamamoto, Vice President and General Manager of Mobile Communication Systems Division of Seiko Instruments. "The device made it possible for us to integrate HSDPA support and receiver diversity in a compact flash-sized card. This new solution will enable Softbank Mobile’s business and private customers to take advantage of high-speed Internet applications, to download emails and share content even when on the move."

“We are very pleased to have our SMARTi 3G selected by Seiko Instruments and are proud that our combined solution was able to successfully pass the rigorous testing criteria of Softbank Mobile,” said Stefan Wolff, Vice President, Communication Solutions business group and General Manager of the RF Engine business unit at Infineon. “This success is a result of our leading technological expertise and the great relations with our customer SII.”

The SMARTi 3G is the world's first cellular transceiver IC that supports all currently specified frequency bands designated for all UMTS networks around the world.

A standard analog interface ensures compatibility with the majority of existing 3G base band processors. The SMARTi 3G supports HSDPA (High Speed Downlink Packet Access) Category 8 with the downlink data rate of 7.2 Mbps. Full compliance with HSDPA requirements for higher data rates gives system designers a simple migration path to next generation UMTS handset based on the same architecture.
