Eaton Electric Systems has the released the nRF2401, 2.4GHz transceiver from Nordic VLSI.
Key feature of the receiver is its ability to receive on 2 channels simultaneously, for instance from a wireless mouse and keyboard transmitting at the same time, thereby eliminating the need for adding RX modules, with a resultant halving of costs and saving of space.
In addition, the nRF2401 takes advantage of the high data rate available - up to 1Mbit/sec. It uses an on-chip FIFO allowing the microcontroller to clock in data at a low data rate and the RF transceiver to transmit at a very high rate.
This feature, called ShockBurst, enables extreme reduction in power consumption - typically averaging 95% with a 10kbit/sec continuous link.
"For customers requiring wireless functionality, but where local regulations has prohibited the use of RF technology, the nRF2401 represents the ideal solution,” says Geir Langeland, Nordic VLSI's product manager.
“It is small, it uses extremely little current, and can operate on most known battery technologies. Effectively it can replace IR and typical 27MHz communication in most applications"
Features of the nRF2401 include 2.4GHz operation with 79 base channels (49 extra channels for certain territories), 1.9-3.6V voltage supply and 0-1Mbit/sec data rate, 0dBm output power, CRC and address computation, ShockBurst/direct mode, 15mA peak RX current, address stripping and CRC computation in RX, clock recovery on data and simultaneous dual receiver topology.
