CYW20736 Single-Chip Bluetooth Low Energy System-On-Chip The Cypress CYW20736 is a an advanced Bluetooth Low Energy SoC that supports wireless charging profile. The CYW20736 is designed to support the entire spectrum of Bluetooth Low Energy use cases for the medical, home automation, accessory, sensor, Internet Of Things, and wearable market segments. The CYW20736 radio has been designed to provide low power, low cost, and robust communications for applications operating in the globally available 2.4 GHz unlicensed Industrial, Scientific, and Medical (ISM) band. The single-chip Bluetooth low energy SoC is a monolithic component implemented in a standard digital CMOS process and requires minimal external components to make a fully compliant Bluetooth device. The CYW20736 is available in a 32-pin, 5 mm 5 mm 32-QFN package as well as WLCSP. CYW20736 device is supported in WICED SDK 2.x 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.
