CYW89820
AIROC™ CYW89820 Automotive Bluetooth® system on chip
The AIROC™ CYW89820 Automotive Bluetooth® & Bluetooth® LE SoC is a Bluetooth® 5.4 core spec compliant device for automotive and industrial applications. Manufactured using the industry's advanced 40 nm CMOS low-power process, the CYW89820 is a highly integrated device which delivers up to 11.5 dBm transmit output power in LE and BR modes and up to 2.5 dBm in EDR mode, reducing the device footprint and the costs associated with implementing Bluetooth® solutions.
The AIROC™ CYW89820 brings the latest Bluetooth® technology to automotive applications and offers automotive Grade 2 (-40C to + 105C) ambient temperature performance. The AIROC™ CYW89820 is tested to Automotive Electronics Council AEC-Q100 environmental stress guidelines and is manufactured in ISO9001 approved and TS16949 certified facilities.
The AIROC™ CYW89820 is supported by the AIROC™ Bluetooth® SDK in ModusToolbox™ software and tools with code examples to support rapid development of Bluetooth® use cases for industrial (access control, asset tracking, factory automation, logistics management, sensors) and automotive (car access, car sharing, keyless entry, passive entry and passive start, wireless diagnostics/OBD, sensors, and cable replacement).
