GENEVA--STMicroelectronics today announced a partnership with San Diego-based Dot Wireless Inc. to jointly develop Code Division Multiple Access technology and CDMA baseband chips for third-generation cellular telephones.
Under the agreement, STMicro and Dot Wireless said they have set up an engineering team in San Diego to co-develop intellectual property (IP) for baseband functions, embedded protocol software, and transceiver reference designs. The alliance aims to leverage Dot Wireless' technology for the IS-95 CDMA standard and STMicro's ST100 digital signal processor architecture, 0.18-micron CMOS process, and system IP functions.
The partners intend to combine their technologies to provide customers with "a complete source for 3G baseband, software and transceiver solutions," said Rick Kornfeld, CEO and president of Dot Wireless. He added that STMicro's advanced chip-processing capabilities will help drive down the costs for cellular phones with system-level integration on ICs.
The alliance also aims to create a flexible platform for CDMA designs. "Our plan is to develop scaleable 3G platforms for bringing customer-specified products to market quickly," said Mark Hopkins, U.S. director for STMicro's Wireless Division. "These standards-based platforms will combine Dot's leading-edge CDMA technology with our high-performance, low-power ST100 DSP architecture."
One of the tricks in delivering 3G cellular phone solution with CDMA is providing high levels of chip integration while the standards continue to evolve in the marketplace, noted Marie-Helene Sibille, General Manager of STMicro's Wireless Communication Division, Telecommunication and Peripherals/Automotive Groups. He added that the new partnership between STMicro and Dot Wireless will combine the tools and technologies for 3G cellular phone systems and other emerging applications.
