Sunplus named as the first TTPCom 3G Baseband Chipset Design Customer

Cambridge, UK -- June 22, 2006 - TTPCom Limited (“TTPCom”), and Sunplus Technology Co. Ltd. ("Sunplus", TAIEX: 2401, LSE: SUPD), the world's leading consumer IC design company, today reveal that Sunplus is the first licensee of CBEmacro 3G, the latest member of TTPCom’s proven and warranted Cellular Baseband Engine family. CBEmacro 3G includes all software and hardware elements required to implement the communications subsystem of the next generation of 3G cellular communications processors.

The modem subsystem of a cellular chipset is no longer viewed by semiconductor vendors as a point of differentiation for their products. Instead, multimedia features are now the new battlefield on which they compete. TTPCom’s CBEmacro allows semiconductor vendors to respond to this trend by providing a pre-integrated and validated cellular modem block for use in System on Chip (SoC) designs. Customers that implement CBEmacro are relieved of the burden of developing and maintaining the modem function in-house. Instead, they can devote their engineering effort to delivering real value in adding new multimedia capabilities in their chipset products. CBEmacro’s proven technology supports rapid market entry for a new breed of silicon vendors with expertise in these areas.

"Cooperating with TTPCom is a strategic decision for us," adds Mr Yarn-Chen Chen, CTO of Sunplus. "We benefit from TTPCom’s proven wireless technologies and protocol software for fast time-to-market. We will continue to work together to deliver new competitive solutions for the handset market."

Tony Milbourn, TTPCom’s managing director comments: "We’re delighted that Sunplus has adopted CBEmacro 3G into its research and development plan for cellular multimedia chipsets. We are bringing together two very complementary strengths to create a compelling wireless multimedia chipset and we look forward to a long cooperation with Sunplus, both in the short term as TTPCom and in the longer term as part of Motorola.”
