IS2083 IS2083 Bluetooth Stereo Audio SoC Data Sheet 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 high- fidelity 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 2 AT receives audio inputs through the Aux-In or I S pin and streams the audio to up to two Bluetooth paired sink devices. Note: Contact your local sales representative for more information about the Software Development Kit (SDK). 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. Features Qualified for Bluetooth v5.0 specification Hands-free Profile (HFP) 1.7.2, Headset Profile (HSP) 1.2, Advanced Audio Distribution Profile (A2DP) 1.3, Serial Port Profile (SPP) 1.2, Audio/Video Remote Control Profile (AVRCP) 1.6 and Phone Book Access Profile (PBAP) 1.2 Bluetooth classic (BR/EDR) and Bluetooth Low Energy General Attribute Profile (GATT) and General Access Profile (GAP) Bluetooth Low Energy Data Length Extension (DLE) and secure connection Software Development Kit 8051 microcontroller debugging 24-bit program counter and Data Pointer modes Multi-Speaker (MSPK) solution Microchip s proprietary solution to connect a central speaker to one or more peripheral speakers With MSPK firmware, the IS2083 can provide Concert mode and Stereo mode Audio Transceiver (AT) solution With AT firmware, the IS2083 can work as either an A2DP source (where IS2083 is the transmitter) or A2DP/HFP sink (where IS2083 is a receiver) Audio Interfaces Stereo line input Two analog microphones One stereo digital microphone Stereo audio Digital-to-Analog Converter (DAC) 2 I S input/output Datasheet DS70005403D-page 1 2019-2021 Microchip Technology Inc. and its subsidiaries IS2083 2 I S Primary clock (MCLK)/reference clock USB, UART and Over-the-Air (OTA) firmware upgrade Built-in lithium-ion and lithium polymer battery charger (up to 350 mA) Integrated 3V and 1.8V configurable switching regulator and Low-Dropout (LDO) Radio Frequency (RF)/Analog Bluetooth 5.0 dual mode RF radio Receive sensitivity: -90 dBm (2 Mbps EDR) Programmable transmit output power: Up to +11 dBm (typical) for Basic Data Rate (BDR) Up to +9.5 dBm (typical) for Enhanced Data Rate (EDR) Integrated Medium Power Amplifier (MPA) and Low Power Amplifier (LPA) MCU Features 8051 8-bit core 8-bit data 24-bit program counter (PC24) mode 24-bit data pointer (DPTR24) mode Operating speed: DC 48 MHz clock input 0.33-1 MIPS/MHz, depending on instruction DSP Voice and Audio Processing 16/32-bit DSP core with enhanced 32-bit precision, single cycle multiplier Synchronous Connection-Oriented (SCO) channel operation Modified Sub-Band Coding (mSBC) decoder for wideband speech Built-in High-definition Clean Audio (HCA) algorithms for both narrowband and wideband speech processing Built-in audio effect algorithms to enhance audio streaming 64 Kbps A-Law, -Law Pulse Code Modulation (PCM) or Continuous Variable Slope Delta (CVSD) modulation for SCO channel operation 8/16 kHz Noise Reduction (NR) 8/16 kHz Acoustic Echo Cancellation (AEC) Packet Loss Concealment (PLC) for SBC and mSBC codecs only Audio Codec Sub-band Codec (SBC), Advanced Audio Codec (AAC) and LDAC Decoding (IS2083BM-2L2 only) 20-bit audio stereo DAC with SNR 95 dB 16-bit audio stereo ADC with SNR 90 dB 2 24-bit, I S digital audio: 96 kHz output sampling frequency 48 kHz input sampling frequency Peripherals Successive Approximation Register Analog-to-Digital Converter (SAR ADC) with dedicated channels: Battery voltage detection and adapter voltage detection Charger thermal protection and ambient temperature detection UART (with hardware flow control) USB (full-speed USB 1.1 interface) 2 I C Host One Pulse Width Modulation (PWM) channel DS70005403D-page 2 Datasheet 2019-2021 Microchip Technology Inc. and its subsidiaries
