PRODUCT SPECIFICATION Single chip 2.4 GHz Transceiver nRF2401A FEATURES APPLICATIONS True single chip GFSK transceiver in a small Wireless mouse, keyboard, joystick 24-pin package (QFN24 5x5mm) Keyless entry Data rate 0 to1Mbps Wireless data communication Only 2 external components Alarm and security systems Multi channel operation Home automation 125 channels Surveillance Channel switching time <200 s. Automotive Support frequency hopping Data slicer / clock recovery of data Telemetry Address and CRC computation Intelligent sports equipment DuoCeiver for simultaneous dual receiver Industrial sensors topology Toys ShockBurst mode for ultra-low power operation and relaxed MCU performance Power supply range: 1.9 to 3.6 V Low supply current (TX), typical 10.5mA peak -5dBm output power Low supply current (RX), typical 18mA peak in receive mode 100 % RF tested No need for external SAW filter World wide use GENERAL DESCRIPTION nRF2401A is a single-chip radio transceiver for the world wide 2.4 - 2.5 GHz ISM band. The transceiver consists of a fully integrated frequency synthesizer, a power amplifier, a crystal oscillator and a modulator. Output power and frequency channels are easily programmable by use of the 3-wire serial interface. Current consumption is very low, only 10.5mA at an output power of -5dBm and 18mA in receive mode. Built-in Power Down modes makes power saving easily realizable.
