SigmaTel Inc. and Infineon Technologies AG have entered into an agreement to offer Bluetooth solutions for portable digital multimedia devices. Under the terms of the agreement, the companies will jointly develop a Bluetooth chip that is optimized for use in digital multimedia devices based on SigmaTel's portable multimedia system on chip (SoC) solutions. The chip will make use of SigmaTel's optimized radio architecture and Infineon's expertise in Bluetooth technology, chip design, CMOS process technology, and manufacturing know-how. SigmaTel and Infineon believe this solution will enable widespread adoption of Bluetooth technology in even the most cost-sensitive, power and space-constrained applications, such as MP3 players or stereo headsets. The chip will be exclusively marketed by SigmaTel.

“SigmaTel is working on internal developments, as well as relationships with world-class companies like Infineon, to offer customers wireless capabilities in conjunction with our SoC solutions,” said Ron Edgerton, president and CEO of SigmaTel.

“The Bluetooth chip is optimized for low power consumption and minimum size,” said Thomas Pollakowski, vice president and general manager of the connectivity business unit at Infineon Technologies.”

Infineon's BlueMoon UniCellular supports basic and enhanced data rate together with minimized power consumption and excellent RF performance, providing an outstanding receiver sensitivity of -90 dBm. Prior to the availability of the optimized Bluetooth solution, SigmaTel will begin offering Infineon's BlueMoon UniCellular (PMB8753) Bluetooth 2.0 solution featuring enhanced data rate (EDR) functionality as part of its STMP3600 MP3 player reference design kits (RDKs). The reference design will provide a turnkey system, including the Bluetooth upper stack software and relevant Bluetooth profiles. The design will also be BQB certified and UnplugFest tested, reducing customer development costs and time to market.
