CYW20721：用于音频的增强型低功耗BREDRBLE蓝牙5.0 SOC
音频是个专业术语，音频一词已用作一般性描述音频范围内和声音有关的设备及其作用。人类能够听到的所有声音都称之为音频，它可能包括噪音等。声音被录制下来以后，无论是说话声、歌声、乐器都可以通过数字音乐软件处理，或是把它制作成CD，这时候所有的声音没有改变，因为CD本来就是音频文件的一种类型。而音频只是储存在计算机里的声音。如果有计算机再加上相应的音频卡——就是我们经常说的声卡，我们可以把所有的声音录制下来，声音的声学特性如音的高低等都可以用计算机硬盘文件的方式储存下来。部分文件列表

CYW20721
Enhanced Low Power, BR/EDR/BLE
Bluetooth 5.0 SOC for Audio
The CYW20721 is a BT 5.0-compliant, stand-alone baseband processor with an integrated 2.4 GHz transceiver with BLE, EDR and
BR. The device is intended for use in audio, IOT, sensors (medical, home, security, and so forth) and human interface device (HID)
applications. Manufactured using an advanced 40nm CMOS low-power fabrication process, the CYW20721 employs high level of
integration to reduce external components, thereby minimizing application footprint and costs.
This datasheet provides details of the functional, operational, and electrical characteristics of the CYW20721 device. It is intended for
hardware, design, application, and OEM engineers.
