Texas Instruments CC2571
the CC2571 supports eight ANT channels. The CC2570/71 can be connected to a host MCU (such as an MSP430) through a UART or SPI serial interface and accessed through a set of API calls. The majority of the ANT protocol is built into the CC2570/71, including the ANT-FS file system functionality; only the application and profile layers must reside on the host MCU, thus keeping host MCU memory requirements to a minimum.FEATURES
