Following the launch of the 2,4 GHz nRF2401 transceiver for global ISM application, Nordic VLSI has announced that the component has been released for full volume production.
Since releasing the nRF2401 late last year, a number of world-leading companies have been evaluating the device and have received samples and evaluation boards. "The interest from customers has been phenomenal and we have had a hard time supplying enough evaluation boards and samples. The customers have been particularly excited about the ShockBurst feature that allows them to significantly cut cost and power consumption," says product manager Geir Langeland.
The nRF2401 is designed for wireless transceiver applications in wireless game controllers, PC peripherals, wireless headsets, sports and leisure equipment, toys, RF-ID, remote control, and interactive equipment. All configuration of the nRF2401 transceiver is done via a standard serial interface.
The nRF2401 is a highly integrated component for wireless communication. It is manufactured in ultra modern 0,18 µm CMOS process. The entire transceiver, including all inductors and filters, is integrated in a single chip. The only external components needed to make a complete RF system is a crystal and a resistor.
Innovative embedded features reduce cost and current consumption. The receiver can receive on two channels simultaneously (DuoCeiver), for instance from a wireless mouse and keyboard transmitting at the same time, thus eliminating the need for adding two separate RX modules, and it allows for full 2 Mbps receive.
The nRF2401 takes full advantage of the high data-rate available - up to 1 Mbit/sec. It uses an on-chip FIFO that allows the micro to clock in- and out the payload at a low data rate, and it simultaneously performs CRC and address computation in both TX and RX mode. This feature (called ShockBurst) enables an extreme reduction in power consumption and the possibility of using low-end microcontrollers to reduce the overall BOM. Typical attainable reduction in power consumption can average 95% with a 10 Kbps continuous link.
Maximum current consumption is less than 15 mA in receive mode, and 8 mA in transmit mode, at -5 dBm. The total solution fits into a 5 x 5 mm package.
