CC257X
The CC2570 and CC2571 are ANT RF
network processors that implement
the easy-to-use, power-efficient ANT
protocol. The CC2570 supports 1 ANT
channel, while the CC2571 supports
8 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 applica-
tion and profile layers need to reside
on the host MCU, thus keeping host
MCU memory requirements to a
minimum.
