SYSTEM DESCRIPTION

The CC8520 is a 2.4GHz wireless SoC operating in the 2.4 GHz ISM band designed for streaming digital

audio wirelessly. It is designated to operate autonomously (without any host MCU) but certain aspects of

operation can be controlled by a host MCU.

Before operation, the CC8520 must be programmed with a user-specific FW image, which can be created

using the PPW Configurator [1]. The configuration file can be programmed into the on-chip Flash memory by

using the PPW Configurator and the CC Debugger [2] and is also programmable in a production line. The

configuration image contains information identifying the device as a master or a slave, how many channels are

supported, the direction of the audio channels, HID support, audio device supported and more.

If CC8520 is configured as a slave, it will automatically start searching for a valid audio network. If configured

as a master, it will start a new network. As soon as a network is formed, audio transmission will commence.

The CC8520 will automatically configure an attached supported audio IC (see compatibility list for a list of

supported ICs in chapter 3).

Other audio devices

The CC8520 is compatible with any I2S-based audio device that does not need to be configured at power-up

and that is compatible with the requirements listed in the audio interface (Chapter 6). It is also compatible with

a wide range of TI DSPs using an I2S interface.
