BCM89359 Advance Data Sheet
Bluetooth Subsystem Overview
Section 4: Bluetooth Subsystem Overview
The Broadcom BCM89359 is a Bluetooth 4.1 + EDR-compliant, baseband processor/2.4 GHz transceiver with
an integrated dual-band radio. 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 BCM89359 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 BCM89359
incorporates all Bluetooth 4.1 features including Secure Simple Pairing, Sniff Subrating, and Encryption Pause
and Resume.
The BCM89359 Bluetooth radio transceiver provides enhanced radio performance to meet the most stringent
mobile phone temperature applications and the tightest integration into mobile handsets and portable devices.
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.
