PRODUCT SPECIFICATION
nRF2401 Single Chip 2.4 GHz Radio Transceiver
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 extremely power reduction.
When operating the nRF2401 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
nRF2401 offers the following benefits:
The nRF2401 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.
ShockBurst™ principle
When the nRF2401 is configured in ShockBurst™, TX or RX operation is conducted
in the following way (10 kbps for the example only).

Highly reduced current consumption
Lower system cost (facilitates use of less expensive micro controller)
Greatly reduced risk of ‘on-air’ collisions due to short transmission time
