Data Sheet
BCM89071
Single-Chip Automotive Grade Bluetooth
Transceiver and Baseband Processor
GENERAL DESCRIPTION
The Broadcom^® BCM89071 is a monolithic, single-
chip, Bluetooth 4.1 compliant, stand-alone
baseband processor with an integrated 2.4 GHz
transceiver. Manufactured using the industry's most
advanced 65 nm CMOS low-power process, the
BCM89071 employs the highest level of integration,
eliminating all critical external components, and
thereby minimizing the device’s footprint and costs
associated with the implementation of Bluetooth
solutions.
The BCM89071 brings current mobile connectivity
technology to automotive radio applications and
offers automotive Grade 3 (–40°C to +85°C ambient
operating temperature range) performance. The
BCM89071 is tested to Automotive Electronics
Council (AEC) guidelines (AEC-Q100) for
environmental stress testing and is manufactured in
ISO9001 approved and TS16949 certified facilities.
