NRF2401A Datasheet, PDF (14/38 Pages) List of Unclassifed Manufacturers – Single chip 2.4 GHz Transceiver

PRODUCT SPECIFICATION
nRF2401A Single Chip 2.4 GHz Radio Transceiver
Configuration Mode
In configuration mode a configuration word of up to 15 bytes is downloaded to
nRF2401A. This is done through a simple 3-wire interface (CS, CLK1 and DATA).
For more information on configuration please refer to the nRF2401A Device
configuration chapter on page16.
Stand-By Mode
Stand by mode is used to minimize average current consumption while maintaining
short start up times. In this mode, part of the crystal oscillator is active. Current
consumption is dependent on crystal frequency (Ex: 12 µA @ 4 MHz, 32 µA @ 16
MHz). The configuration word content is maintained during stand by.
Power Down Mode
In power down the nRF2401A is disabled with minimal current consumption,
typically less than 1µA. Entering this mode when the device is not active minimizes
average current consumption, maximizing battery lifetime. The configuration word
content is maintained during power down.
