Bluetooth Baseband IC Series

Thu, 04/04/2002 - 8:30am
Fujitsu announced a pair of new Bluetooth™ Baseband ICs for hands-free cellular phones and other mobile wireless applications. Fujitsu's new MB86C00 and MBG011 baseband ICs comply with the Bluetooth v1.1 specification. They provide all baseband signal processing and protocol hardware required by Bluetooth radios, and support a variety of external RF ICs. As an added feature, the MBG011 version integrates a 2-Mbit flash memory in the package. The new ICs also support Fujitsu's MB86437 audio codec.

The MB86C00 and MBG011 each include an embedded ARM7 TDMI processor with firmware that implements the Bluetooth protocol. A Bluetooth-compliant Synchronous Connection Oriented (SCO) codec incorporated in both ICs supports A-Law, micro-Law and 12-to-16 bit linear CVSD and SCO channel capabilities. For interfacing, the ICs provide pair of popular host controllers — USB version 1.1 for PC applications, along with a 1-Mbits/sec UART for Bluetooth system applications. Also on board are an IEEE 1149.1 JTAG port and a flexible analog frequency synthesizer PLL, which supports reference clock frequencies ranging from 8 MHz to 32 MHz.
