描述 Description

The IS2021 Stereo Audio Chip is a compact, highly integrated, CMOS single-chip RF and baseband IC for Bluetooth 5.0 with Enhanced Data Rate 2.4GHz applications. This chip is fully compliant with Bluetooth specification and completely backward-compatible with Bluetooth 3.0, 2.0 or 1.2 systems.? It incorporates Bluetooth 1M/2M/3Mbps RF, single-cycle 8bit MCU, TX/RX modem, 5-port memory controller, task/hopping controller, UART interface, and Microchip’s own Bluetooth software stack to achieve the required BT v5.0 with EDR functions.To provide the superior audio and voice quality, it also integrates a DSP co-processor, a PLL, and a CODEC dedicated for voice and audio applications.? For voice, not only basic CVSD encoding and decoding but also enhanced noise reduction and echo cancellation are implemented by the built-in DSP to achieve better quality in both sending and receiving sides. For the enhanced audio applications, SBC/AAC_LC decoding functions can be also carried out by DSP to satisfy Bluetooth A2DP requirements.In addition, to minimize the external components required for portable devices, a battery voltage sensor, battery charger, a switching regulator and LDO are integrated to reduce system BOM cost for various Bluetooth applications.
