DEVICE OVERVIEW

Microchip’s RN52 Bluetooth audio module provides a

highly integrated solution for delivering high-quality ste-

reo audio in a small form factor. It combines a class 2

Bluetooth radio with an embedded DSP processor. The

module is programmed and controlled with a simple

ASCII command set.

The RN52 module complies with Bluetooth specifica-

tion version 3.0. It integrates an RF radio and a base-

band controller making it a complete Bluetooth

subsystem. The RN52 supports a variety of profiles

including A2DP, AVRCP, HSP/HFP, SPP and iAP. It

provides a UART interface, several user programmable

I/O pins, stereo speaker outputs, microphone inputs,

digital audio interface and a USB port. Standard RN52

and its variants support A2DP, AVRCP, HFP, SPP and

iAP in the capacity of Bluetooth Slave role. RN52SRC

supports A2DP, AVRCP, HFP in the capacity of

Bluetooth Master role.

RN52 supports wireless iAP profile advertising which is

discoverable by iOS devices. An external host micro-

controller is required to implement the iAP protocol and

communicate with the authentication coprocessor

while using the RN52 as a data pipe only to transfer the

iAP protocol data over Bluetooth back and forth with

the Apple device. A PIC® microcontroller can be used

to implement the iAP protocol using the Microchip MFi

Library.

module. Table 1-2 and Table 1-3 provide the module’s

weight, dimensions and electrical characteristics.

Figure 1-1 shows the module’s dimensions and

Figure 1-2 shows recommended landing pattern and

layout.
