BCM20705 Data Sheet
Overview
Section 1: Overview
The Broadcom® BCM20705 complies with Bluetooth Core Specification, version 4.1 and is designed for use in
standard Host Controller Interface (HCI) UART and HCI USB applications. 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.
