NRF2401AG

The Nordic nRF2401A is a highly integrated, ultra low power (ULP) 1Mbps RF transceiver IC for the 2.4GHz ISM (Industrial, Scientific and Medical) band. With peak RX/TX currents lower than 20mA, a sub μA power down mode, advanced power management, and a 1.9 to 3.6V supply range, the nRF2401A provides a true ULP solution enabling months to years of battery lifetime when running from coin cells or AA/AAA batteries. In addition, its ShockBurst hardware protocol accelerator offloads time critical protocol functions from the application microcontroller enabling the implementation of advanced and robust wireless connectivity with low cost 3rd-party microcontrollers. The nRF2401A integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the ShockBurst hardware protocol accelerator supporting a high-speed SPI interface for the application controller. No external loop filter, resonators, or VCO varactor diodes are required, only a low cost 16MHz ±30ppm crystal, matching circuitry, and antenna.
