Table 6 Overview of Operational Modes of nRF2402/nRF2402G.
Active Modes
The nRF2402/nRF2402G has two transmit modes:
• ShockBurst™
• Direct Mode
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/nRF2402G (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/nRF2402G offers the following benefits:
• 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
The nRF2402/nRF2402G 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.
