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.

PUREPATH-WL-CFG — PurePath™ 無線配置器
CC85XX 裝置在 TI 交付時未經過編程，需使用韌體進行編程才能在客戶應用程式中執行。根據不同的參數，例如網路和應用程式角色 (音訊傳送器、音訊接收器等)、音訊串流方式和應用電路設計，需要使用不同的韌體。
PurePath 無線配置器 (PPWC) 是一款圖形 PC 工具，用於與 CC85XX 裝置配合使用，不需要額外的第三方工具。PPWC 處理預編譯的圖像文件。根據使用者的輸入，PPWC 將修補這些內容，以生成可下載的韌體影像。設計人員隨後將能透過 CC 偵錯器工具 (包含在 CC85XXDK 中) 直接從 PPWC 對 CC85XX 裝置進行編程，或輸出至 Intel 十六進位檔案 (...)
