CYW20704
Single-Chip Bluetooth Transceiver
and Baseband Processor
The Cypress CYW20704 is a monolithic, single-chip, Bluetooth 4.1+ HS-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.
Cypress 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.
