The nRF24AP1 is an ultra-low power single-chip radio transceiver with embedded ANT
protocol for personal area networks. The transceiver’s RF operating frequency range falls
within the world-wide 2.4 - 2.5 GHz RF ISM band, allowing for regulatory compliance
and product sales into global markets.

PRODUCT SPECIFICATION
nRF24AP1 Single Chip 2.4 GHz Radio Transceiver with Embedded ANT Protocol
The transceiver consists of the ANT fully integrated protocol engine, frequency
synthesizer, power amplifier, crystal oscillator and modulator, and can be interfaced to a
host micro controller over either a synchronous or asynchronous serial interface.
Designed to run on a wrist-watch coin cell battery, current consumption of the device is
extremely low - a typical sensor application can operate on approximately 30µA average
current consumption. Short, low peak current transitions are battery friendly.
The embedded ANT protocol makes for easy, low cost integration. Eliminating the need
for 3rd party RF protocol implementation, the on-chip ANT protocol combined with the
2.4GHz transceiver enables system and application developers to interact with the
nRF24AP1 as a black box wireless solution. The simple serial interface (asynchronous or
synchronous) to the device allows for flexibility and scalability from ultra-low power
sensors (30µA) through to higher data rate (20kbps) applications implemented in a
multitude of network configurations. Networks can be scaled from as little as two nodes
to thousands. With 232 unique IDs, multiple radio frequencies, public and private network
management and scalable data rates, an unlimited number of network configurations and
applications are possible.
Prior to reading this document, the “ANT Message Protocol and Usage” document should
be read to gain understanding of the ANT protocol capabilities.
