n is a highly integrated, ultra

low power (ULP)

2Mbps

transceiver IC for the

2.4GHz

ISM

(Industrial, Scienti c and Medical)

band

2.400

2.4835

GHz.

The Nordic n integrates a complete

2.4GHz

transceiver

, RF

synthesizer

, and

baseband logic

including the

hardware protocol accelerator (Enhanced ShockBurst)
supporting a high-speed SPI interface for the application
controller.

With peak RX/TX currents lower than

14mA

, a sub uA power

down mode, advanced power management, and a

1.9

3.6V

supply range, the n provides a true ULP solution
enabling months to years of battery life from coin cell or AA/AAA
batteries.
