The latest device in Nordic Semiconductor's portfolio of 2,4 GHz wireless ICs is claimed to merge high speed with ultra-low power and cost. The nRF24L01 will enable applications such as wireless desktops and intelligent sports equipment and is also a good fit for advanced multimedia solutions like Voice over IP (VoIP). According to Nordic this is possible through the innovative MultiCeiver solution in which on-chip hardware supports up to six simultaneous wireless devices.
The chips relaxed external component specification helps facilitate ultra-low solution cost (±60 ppm crystal, chip inductors in antenna match; no need for multilayer PCB) while the 5 V tolerant signal input pads mean no need for level-shifters in USB interfaces. There is also no need for a microcontroller with hardware SPI, even when running a bi-directional link.
The nRF24L01 represents a breakthrough for coin cell battery-operated equipment in the 2,4 GHz frequency band: 12,5 mA peak RX current at 2 Mbps, 11 mA peak TX current @ 0 dBm Pout at 2 Mbit/s; 400 nA supply in power down mode; 32 μA in standby mode.
The nRF24L01 is designed for an easy worldwide regulatory approval. It operates from 1,9 to 3,6 V and comes in a 20 pin 4 x 4 mm QFN package.
