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
keeping host MCU memory requirements to a
minimum.
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.
