BM20/23 Device Overview 1. Device Overview
The BM20 and BM23 stereo module is built around the IS2020S and IS2023S SoCs, respectively, which integrates the Bluetooth radio transceiver, a Power Management Unit (PMU), and a Digital Signal Processor (DSP). The following figure illustrates a typical example of the BM20 module that operates as an independent system or when connected to an MCU.
Figure 1-1. BM20 Typical Application
The following figure illustrates a typical example of the BM23 module connected to an external MCU and a DSP/ Codec.
