CC8520, CC8521, CC8530(cid:15) CC8531 WWW.TI.COM SWRS091F – JUNE 2012 DESCRIPTION The PurePath™ Wireless platform is a cost-effective and low-power solution optimized for wireless transmission of high-quality digital audio. The CC85xx includes a robust built-in wireless audio transmission protocol and can control selected external audio devices. Utilizing numerous coexistence mechanisms allows the CC85xx to avoid interfering with, or being interfered by other 2.4 GHz radio systems. The CC85xx operates autonomously, and can be used with or without an external MCU. An external host processor can be connected through SPI and control some aspects of its operation. The CC85xx interfaces easily with other TI audio ICs and DSPs (using I2S and DSP/TDM interfaces). More details can be found in the CC85xx Family User Guide [2].

CC8520, CC8521, CC8530(cid:15)C8531 WWW.TI.COM SWRS091F – JUNE 2012 This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

CC8520, CC8521, CC8530(cid:15) CC8531 WWW.TI.COM SWRS091F – JUNE 2012 3 SYSTEM DESCRIPTION By employing proprietary technology, referred to as PurePath Wireless, the CC85xx device family provides robust, high-quality, short-range 2.4 GHz wireless digital audio streaming in low-cost single chip solutions. Two or more devices form a PurePath Wireless audio network. Great care has been taken to ensure that this audio network provides gap-less and robust audio streaming in varied environments and that it can coexist amicably with existing wireless technologies in the crowded 2.4 GHz ISM band. Most applications can be implemented without any software development and only require the CC85xx to be connected to an external audio source or sink (such as an audio codec, S/PDIF interface or class-D amplifier) and a few push buttons, switches or LED for human interaction. Advanced applications can interface a host processor or DSP directly to the CC85xx and directly stream audio and control most aspects of device and audio network operation. The complete list of supported audio devices can be found in the PurePath Wireless Configurator [1]. The PurePath Wireless Configurator [1], a PC-based configuration tool, is used to set up the desired functionality and parameters of the target system and then produces firmware images that subsequently must be programmed into the embedded flash memory of each CC85xx. All devices in the CC85xx family interface seamlessly with the CC2590 RF range extender device to allow for even wider RF coverage and improved robustness in difficult environments. 4 DOCUMENT HISTORY Revision Date Description/Changes June 2012 Added 2 Mbit mode (throughout document) and flash endurance SWRS091F numbers.
