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 devices 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 transceivers 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. Table 1.
