RN52 1.0 DEVICE OVERVIEW
iAP in the capacity of Bluetooth Slave role. RN52SRC supports A2DP, AVRCP, HFP in the capacity of Microchip’s RN52 Bluetooth audio module provides a Bluetooth Master role. highly integrated solution for delivering high-quality ste- RN52 supports wireless iAP profile advertising which is reo audio in a small form factor. It combines a class 2 discoverable by iOS devices. An external host micro- Bluetooth radio with an embedded DSP processor. The module is programmed and controlled with a simple controller is required to implement the iAP protocol and communicate with the authentication coprocessor ASCII command set. while using the RN52 as a data pipe only to transfer the The RN52 module complies with Bluetooth specifica- iAP protocol data over Bluetooth back and forth with tion version 3.0. It integrates an RF radio and a base- the Apple device. A PIC® microcontroller can be used band controller making it a complete Bluetooth to implement the iAP protocol using the Microchip MFi subsystem. The RN52 supports a variety of profiles Library. including A2DP, AVRCP, HSP/HFP, SPP and iAP. It provides a UART interface, several user programmable Table 1-1 provides the general specifications for the module. Table 1-2 and Table 1-3 provide the module’s I/O pins, stereo speaker outputs, microphone inputs, weight, dimensions and electrical characteristics. digital audio interface and a USB port. Standard RN52 and its variants support A2DP, AVRCP, HFP, SPP and
