DESCRIPTION

Pairing

The CC2570 and CC2571 are ANT RF network

•

Layout

processors

that

implement

the

easy-to-use,

power-efficient ANT protocol. The CC2570 supports

– Few External Components

one ANT channel, whereas the CC2571 supports

– Reference Designs Available

eight

ANT

channels.

The

CC2570/71

can

be

– 40-Pin, 6-mm × 6-mm QFN Package

connected to a host MCU (such as an MSP430)

through a UART or SPI serial interface and accessed

•

Low Power

through a set of API calls. The majority of the ANT

– Powered Down With Low-Power Timer:

protocol is built into the CC2570/71, including the

µA

ANT-FS file system functionality; only the application

– Powered Down Without Timer: 0.5 µA

and profile layers must reside on the host MCU, thus

keeping host MCU memory requirements to a

– Wide Supply Voltage Range (2 V–3.6 V)

minimum.

•

ANT Protocol Support

The ANT protocol has been designed to be very

– Fully Compatible With the ANT and ANT+™

power-efficient, yet is flexible enough to support

Protocols and Existing ANT Devices

various

network

topologies

(point-to-point,

star,

– Built-In ANT-FS™ Support

connected star, 1-to-N, and N-to-1) and data transfer

– Easy Connection to Host MCU Through

modes

(broadcast,

acknowledged,

burst

data

transfer).

Each

logical

ANT

channel

can

be

Asynchronous or Synchronous Serial

independently configured for one-way or two-way
