Single-Chip Automotive Grade Bluetooth
Transceiver and Baseband Processor
The Cypress CYW89071 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 CYW89071 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 CYW89071 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 CYW89071 is tested to Automotive Electronics Council (AEC)
guidelines (AEC-Q100) for environmental stress testing and is manufactured in ISO9001 approved and TS16949 certified facilities.
Cypress Part Numbering Scheme
Cypress is converting the acquired IoT part numbers from Broadcom to the Cypress part numbering scheme. Due to this conversion,
there is no change in form, fit, or function as a result of offering the device with Cypress part number marking. The table provides
Cypress ordering part number that matches an existing IoT part number.
