1.3 Functional Description

The primary component on the module is the Broadcom BCM20730, which is a

Bluetooth 3.0 compliant basic rate single-chip. The baseband and radio have been

integrated into a single chip implemented in standard digital CMOS. The block diagram of

the module is shown in Figure 1.

Figure 1: Block Diagram

The BT3GMD-B47P employs an integrated ARM CortexTM-M3 microprocessor core

that runs software from the Link Control layer up to the Host Controller Interface (HCI).The

baseband portion of the BT3GMD-B47P performs all the time-critical functions required

for high-performance Bluetooth operations.

The radio incorporates the complete receive and transmit paths, including PLL, VCO,

LNA, PA, upconverter,downconverter, modulator, demodulator, and channel select

filtering.

The BT3GMD-B47P on-chip keyboard scanner is designed to autonomously sample

keys and store them into buffer registers without requiring host microcontroller

intervention. A state machine of three states(Idle, Scan, and Scan-End)controls the

keyscan block.

The module has a SPI interface. The interface has a 16-byte transmit buffer and a

16-byte receive buffer .To support more flexibility for user applications. The module acts

as an SPI master device that supports 1.8V or 3.3V SPI slaves.
