Single-Chip Bluetooth Transceiver and
The CYW20702 is a monolithic, single-chip, Bluetooth 4.0 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 CYW20702 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 CYW20702 is the optimal solution for voice and data applications that require a Bluetooth SIG standard Host Controller Interface
(HCI) via USB, UART H4 or H5, and PCM audio interface support. The CYW20702 radio transceiver’s enhanced radio performance
meets the most stringent industrial temperature application requirements for compact integration into mobile handset and portable
devices. The CYW20702 is fully compatible with all standard TCXO frequencies and provides full radio compatibility, enabling it to
operate simultaneously with GPS and cellular radios.
This document provides engineering design information for the CYW20702, a single-chip Bluetooth transceiver and baseband
processor that provides a complete lower layer Bluetooth protocol stack. The CYW20702 supports Bluetooth 4.0, which includes
support for Enhanced Data Rates (2 Mbps and 3 Mbps) and Low Energy (LE) connections.
The information provided is intended for hardware design engineers who will be incorporating the CYW20702 into their designs.
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.
