BCM43353 Data Sheet
Bluetooth Subsystem Overview
Section 4: Bluetooth Subsystem Overview
The Broadcom BCM43353 is a Bluetooth 4.1 + EDR-compliant, baseband processor/2.4 GHz transceiver. It
features the highest level of integration and eliminates all critical external components, thus minimizing the
footprint, power consumption, and system cost of a Bluetooth solution.
The BCM43353 is the optimal solution for any Bluetooth voice and/or data application. The Bluetooth subsystem
presents a standard Host Controller Interface (HCI) via a high-speed UART and PCM for audio. The BCM43353
incorporates all Bluetooth 4.1 features including Secure Simple Pairing, Sniff Subrating, and Encryption Pause
and Resume.
The BCM43353 Bluetooth radio transceiver provides enhanced radio performance to meet –40°C to +85°C
temperature applications and the tightest integration into automotive and industrial platforms. It is fully
compatible with any of the standard TCXO frequencies and provides full radio compatibility to operate
simultaneously with GPS, WLAN, and cellular radios.
The Bluetooth transmitter also features a Class 1 power amplifier with Class 2 capability.
