Texas Instruments' 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).
The development kit comes pre-programmed with firmware as described in the quick start user’s guide. This firmware is available as an example project in PurePath Wireless Configurator tool (PPWC) PC software. The functionality of the kit can be changed by using PPWC.
