BCM20730
Single-Chip Bluetooth Transceiver for Wireless
Input Devices
GENERAL DESCRIPTION
The Broadcom® BCM20730 is a Bluetooth 3.0-
compliant, stand-alone baseband processor with an
integrated 2.4 GHz transceiver. It is ideal for wireless
input device applications including game controllers,
keyboards, 3D glasses, remote controls, gestural
input devices, and sensor devices. Built-in firmware
adheres to the Bluetooth Human Interface Device
(HID) profile and Bluetooth Device ID profile
specifications.
The BCM20730 radio has been designed to provide
low power, low cost, and robust communications for
applications operating in the globally available
2.4 GHz unlicensed ISM band. It is fully compliant
with Bluetooth Radio Specification 3.0.
The single-chip Bluetooth transceiver is a monolithic
component implemented in a standard digital CMOS
process and requires minimal external components
to make a fully compliant Bluetooth device. The
BCM20730 is available in three package options: a
32-pin, 5 mm × 5 mm QFN, a 40-pin, 6 mm × 6 mm
QFN, and a 64-pin, 7 mm × 7 mm BGA.
