OVERVIEW

The Broadcom® BCM20732 is a Bluetooth Low-

Energy (BLE)-only System-on-a-Chip (SoC). The

BCM20732 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 BLE SoC is a monolithic compo-

nent implemented in a standard digital CMOS pro-

cess and requires minimal external components

to make a fully compliant Bluetooth device. The

BCM20732 is available in a 32-pin, 5 mm × 5 mm

32-QFN package.
