Device Overview

The BM83 stereo audio module is built around the IS2083BM SoC, which integrates the dual-mode baseband,

modem, radio transceiver, PMU, MCU, crystal, and a DSP dedicated for audio and voice applications. Users can

configure the BM83 module by using the SDK or the IS208x_Config_GUI_Tool (Config Tool).

There are two modes of operation:

• Host mode:

– Interfaces with an external MCU over UART for application specific system control.

– The multi-speaker (MSPK) solution can reside on this MCU.

• Embedded mode:

– No external MCU involved.

– BM83 acts as an MCU to control all peripherals to provide various speaker features.

– Integrates the MSPK firmware on the module.

– Simple system control can be implemented in the module MCU by using the SDK.

– DSP parameters such as equalizer settings can be set using the Config Tool.

Note: The SDK and Config Tool are available for download at: http://www.microchip.com/BM83.

The following figure illustrates the Embedded mode and Host mode of the BM83 module.
