Single-chip RF transceiver in the unlicensed 2.4GHz to 2.5GHz ISM band, consisting of an integrated frequency synthesizer, power amplifier, crystal oscillator, demodulator, modulator and Enhanced ShockBurst hardware protocol module. This module takes over the functions of analyzing packet loss and re-sending, reducing the load on the control microcontroller.
Output power, frequency channels and protocol settings are easily programmed via the SPI interface. Consumption currents in operating modes do not exceed 9.0mA when transmitting (-6dBm) and 12.3mA when receiving.
Due to the three-level receive FIFO-buffer, divided into six channels, the transceiver can receive data packets from six different transmitters operating on one frequency channel.
Distinctive features:
frequency range 2.4 GHz ... 2.5 GHz;
80 channels;
channel switching time: 130μs;
mirror channel suppression;
40-bit address support;
data plausibility check: 16-bit CRC;
3-level 32-byte FIFO receive buffer divided into six channels;
32-byte 3-level FIFO transmit buffer;
Serial interface up to 10Mbps ;
input signal levels are 5V tolerant;
supply voltage: 1.9V… 3.6V;
temperature range: -40°C ...+85°C;
body QFN-20.
Applications: wireless computer mice, keyboards, joysticks, access systems, wireless data transmission, systems alarms, home automation, car telemetry, smart sports equipment, industrial sensors, toys.
Typical NRF24L01 wiring.
