Bluetooth Baseband Controller

Motorola => Freescale 

Overview

3 Overview

This section describes the overall system architecture of the MC71000 Bluetooth Baseband Controller. It

highlights the main features and requirements, as well as provides an overview of the operational blocks of

MC71000 Bluetooth Baseband Controller at a system level. The subsequent sections describe the detailed

design requirements by major blocks and functions.

The MC71000 Bluetooth Baseband Controller implements the baseband and host controller interface

(HCI) of the Bluetooth protocol and is specifically designed to meet the immediate market needs for

low-power Bluetooth applications. To improve the total system throughput and reduce component cost and

board size, the MC71000 Bluetooth Baseband Controller integrates a Motorola-unique ARM7TDMI

platform with intelligent peripheral modules focused on communications and system integration. The

MC71000 Bluetooth Baseband Controller includes superior performance features for audio and power

conservation, as well as debug and production test support.

The MC71000 Bluetooth Baseband Controller provides a zero glue logic interface to the MC13180

Bluetooth RF Integrated CircuitC, a 2.4GHz Bluetooth radio for implementing a Bluetooth Class 2

solution. The addition of the MRFIC2408 External Power Amplifier IC provides a Class 1 solution. A

power management chip, MC13181, is also available for headset and mobile phone accessory applications.

The MC13181 integrates power management functions common to these applications. The architecture of

the MC7100 is shown in Figure 1 on page 2.
