CYW20706 Bluetooth SoC for Embedded Wireless Devices The Cypress CYW20706 is a single-chip Bluetooth 4.1-compliant, embedded SoC with an integrated baseband processor, a 2.4 GHz transceiver, an ARM Cortex M3, ROM and RAM, as well as an integrated Bluetooth stack. Manufactured using an advanced 40 nm CMOS low-power process, the CYW20706 employs high levels of integration reduce external components, thereby minimizing the device s footprint and the costs associated with implementing Bluetooth solutions. The CYW20706 is the optimal solution for embedded and IoT applications. Built-in ROM firmware provides access to both Bluetooth Low Energy (SMART) and Bluetooth Classic (SMART READY). 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.
