ARM-Powered Baseband Chips Comply With Bluetooth v1.1

Embedding an ARM7TDMI processor with firmware implementing the Bluetooth protocol, the MB86C00 and MBG011 ICs provide all baseband signal processing and protocol hardware required by Bluetooth radios. And they support a variety of external RF ICs, including FujitsuÕs MB15H101A, ConexantÕs CX72303, and Silicon WaveÕs SiW1502. And an on-chip Bluetooth-compliant Synchronous Connection Oriented (SCO) codec supports A-Law, micro-Law and 12- to 16-bit linear CVSD and SCO channel capabilities. The devices also feature a pair of popular host controllers: an USB v1.1 for PC applications and a 1-Mb/s UART for Bluetooth systems. Also on-chip are an IEEE 1149.1 JTAG port and a flexible analog frequency synthesizer PLL that supports reference clock frequencies from 8 to 32 MHz. MBG011 chip also integrates two Mb of flash memory, eliminating the need for external flash. The Bluetooth v1.1-compliant ICs come in 8 x 8-mm, 176-lead FBGA packages and have a starting price of $10 each. FUJITSU MICROELECTRONICS AMERICA INC., San Jose, CA. (800) 866-8608.
