PRODUCT SPECIFICATION
nRF2402 Single Chip 2.4 GHz Radio Transmitter
MODES OF OPERATION
Overview of Operational Modes
The nRF2402 can be set in the following main modes depending on three control
pins:
Active Modes
The nRF2402 has two transmit modes:
The device functionality in these modes is determined by the content of a
configuration word. This configuration word is presented in the configuration section.
ShockBurst™
The ShockBurst™ technology uses on-chip FIFO to clock in data at a low data rate
and transmit at a very high rate thus enabling extreme reduction in power
consumption.
When operating the nRF2402 (in co-operation with nRF2401/nRF24E1) in
ShockBurst™, you gain access to the high data rates (1 Mbps) offered by the 2.4 GHz
band without the need of a costly, high-speed micro controller (MCU) for data
processing.
By putting all high speed signal processing related to RF protocol on-chip, the
nRF2402 offers the following benefits:
The nRF2402 can be programmed using a simple 3-wire interface where the data rate
is decided by the speed of the micro controller.
By allowing the digital part of the application to run at low speed while maximizing
the data rate on the RF link, the nRF ShockBurst™ mode reduces the average current
consumption in applications considerably.
