DESCRIPTION  
The CC2570 and CC2571 are ANT RF network  
processors that implement the easy-to-use,  
power-efficient ANT protocol. The CC2570 supports  
one ANT channel, whereas 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

ANT Protocol Support  
The ANT protocol has been designed to be very  
power-efficient, yet is flexible enough to support  
various network topologies (point-to-point, star,  
connected star, 1-to-N, and N-to-1) and data transfer  
modes (broadcast, acknowledged, burst data  
transfer). Each logical ANT channel can be  
independently configured for one-way or two-way  
operation, depending on requirements of the  
application.  
Fully Compatible With the ANT and ANT+™  
Protocols and Existing ANT Devices  
Built-In ANT-FSSupport  
Easy Connection to Host MCU Through  
Asynchronous or Synchronous Serial  
Interface
