Renesas Technology has secured a $65 million, three-year development contract from Japanese mobile operator NTT DoCoMo for a single-chip baseband device to be used in dual-mode handsets operating on W-CDMA and GSM/GPRS capable networks.

The partners will combine W-CDMA technology developed by NTT DoCoMo with Renesas Technology's SH-X based multimedia application processor core, dubbed the SH-Mobile 4A.

The deal is the first of its type for Renesas, according to Matthew Trowbridge, the company's European CEO. "DoCoMo has already used this business model very successfully to speed the development of handsets and the uptake of new services, and we are delighted they have chosen our applications processor as the basis of single-chip, dual-mode parts for third generation handsets," Trowbridge told

Samples of the device are expected to be available by early 2006.

Renesas will supply chips to handset makers who can use DoCoMo's networks based on both W-CDMA 3G specifications as well as GSM/GPRS. The operator will receive a license fee for each handset sold for the upfront development investment.

The contract is nonexclusive, and Trowbridge said Renesas is already "discussing similar deals with other operators worldwide. Several operators are now keen to follow DoCoMo's example."

He said the deal is a major boost to the SH-Mobile architecture "that is already used in about 50 percent of the mobile handsets that use an applications processor."

The core to be used in the DoCoMo project is a version of the SH-X two-way superscalar device that is already in development capable of 4,500Mips/W. Versions are already used in car information systems.
