The CYW20704 is a monolithic, single-chip, Bluetooth 5.0 compliant, stand-alone baseband processor with an integrated 2.4 GHz transceiver. Manufactured using the industry's most advanced 40 nm CMOS low-power process, the CYW20704 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 CYW20704 is the optimal solution for voice and data applications that require a Bluetooth SIG standard Host Controller Interface (HCI) via USB, UART H4, and PCM audio interface support.

The CYW20704 transceiver’s enhanced radio performance meets the most stringent industrial temperature application requirements for compact integration into mobile handset and portable devices. The CYW20704 provides full radio compatibility, enabling it to operate simultaneously with GPS and cellular radios.
