CYW20706
Embedded Bluetooth 4.2 SoC with MCU, Bluetooth
Transceiver, and Baseband Processor
The Cypress CYW20706 is a monolithic, single-chip, Bluetooth 4.2 + HS compliant SOC, comprising a baseband processor, an ARM
Cortex-M3 processor, and an integrated transceiver. It is designed for use in embedded applications, with on-chip support for an
embedded stack. Manufactured using the industry's most advanced 40 nm CMOS low-power process, the CYW20706 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 CYW20706 is the optimal solution for voice, data, home automation, accessories and other applications that require a Bluetooth
SIG standards-compliant interface. The CYW20706 supports a host command interface (HCI) through USB or UART and also
supports PCM audio.
The CYW20706 transceiver’s enhanced radio performance meets the most stringent industrial temperature application requirements
for compact integration into mobile handset and portable devices. The CYW20706 provides full radio compatibility, enabling it to
operate simultaneously with GPS and cellular radios.
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.
