BCM89071 Data Sheet
Overview
Section 1: Overview
The Broadcom BCM89071 complies with the Bluetooth Core Specification, version 4.1 and is designed for use
with a standard Host Controller Interface (HCI) UART. The combination of the Bluetooth Baseband Core (BBC),
a Peripheral Transport Unit (PTU), and an ARM^®-based microprocessor with on-chip ROM provides a complete
lower layer Bluetooth protocol stack, including the Link Controller (LC), Link Manager (LM), and HCI.
Major Features
Core features of the BCM89071 include:
• Support for Bluetooth 4.1 + EDR, including the following options:
– A whitelist size of 25
– Enhanced Power Control
– HCI Read Encryption Key Size command
• Full support for Bluetooth 2.1 + EDR additional features:
– Secure Simple Pairing (SSP)
– Encryption Pause Resume (EPR)
– Enhance Inquiry Response (EIR)
– Link Supervision Time Out (LSTO)
– Sniff SubRating (SSR)
– Erroneous Data (ED)
– Packet Boundary Flag (PBF)
• Built-in Low Drop-Out (LDO) regulators (2)
– 1.63 to 5.5V input voltage range
– 1.8 to 3.3V intermediate programmable output voltage
• Integrated RF section
– Single-ended, 50 RF interface
– Built-in TX/RX switch functionality
– TX Class 1 output power capability
– -88 dBm RX sensitivity basic rate
• Supports maximum Bluetooth data rates over HCI UART and SPI interfaces
• Multipoint operation, with up to seven active slaves
– Maximum of seven simultaneous active ACL links
– Maximum of three simultaneous active SCO and eSCO links, with Scatternet support
• Scatternet operation, with up to four active piconets (with background scan and support for ScatterMode)
• High-speed HCI UART transport support
– H4 five-wire UART (four signal wires, one ground wire)
– H5 three-wire UART (two signal wires, one ground wire)
