Introduction

The IS2083 is a System-on-Chip (SoC) for dual mode Bluetooth stereo audio applications. It contains an on-board Bluetooth stack, audio profiles and supports 24-bit/96 kHz high-resolution (Hi-Res) audio formats to enable highfidelity wireless audio. An integrated Digital Signal Processor (DSP) decodes (LDAC, Advanced Audio Codec (AAC), and Sub-band Codec (SBC) codecs) and executes advanced audio and voice processing (wideband speech, Acoustic Echo Cancellation (AEC), and Noise Reduction (NR)). This platform provides a Microcontroller (MCU) core for application implementation via Software Development Kit (SDK) with debug support and a GUI (Config Tool) tool for easy customization of peripheral settings and DSP functionality.

Additionally, the Audio Transceiver (AT) solution enables Bluetooth capability in non-Bluetooth Audio equipment. The AT receives audio inputs through the Aux-In or Pi I²S pin and streams the audio to up to two Bluetooth paired sink devices.

The IS2083 SoC is offered in a BGA package and contains in-package Flash, and is referred to as IS2083BM.

The IS2083BM supports an Over-the-Air (OTA) firmware upgrade and controls the end-application via Bluetooth Low Energy using the Microchip Bluetooth Audio (MBA) mobile app.
