PRODUCT SPECIFICATION
nRF2402 Single Chip 2.4 GHz Radio Transmitter
ShockBurst™ principle
When the nRF2402 is configured in ShockBurst™, TX operation is conducted in the
following way (10 kbps for this example only).
nRF2402 ShockBurst™ Transmit:
MCU interface pins: CE, CLK, DIN
Nordic Semiconductor ASA
Revision: 2.1

1. When the application MCU has data to send, set CE high. This activates
2. The address of the receiving node (RX address) and payload data is
3. MCU sets CE low, this activates a nRF2402 ShockBurst™ transmission.
