CYW20732A0
Single-Chip
Bluetooth Low-Energy Only SoC
The Cypress CYW20732A0 is a Bluetooth Low-Energy (BLE)-only SoC. The CYW20732A0 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, Scien-
tific, and Medical (ISM) band.
The single-chip BLE 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 CYW20732A0 is available in a 32-pin, 5 mm × 5 mm 32-QFN package.
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.
