GENERAL DESCRIPTION
nRF2402 is the Industry's smallest, lowest cost, lowest current consumption and low voltage supply 2.4GHz RF transmitter. It provides global wireless equipment vendors with global 2.4GHz technology at the price and complexity of lower frequencies. The nRF2402, ideally complements the higly successfulnRF2401 transceiver offering vendors with unidirectional equipment a lower cost alternative. The nRF2402 is a highly integrated component for wireless communication manufactured in an ultra modern 0.18mm CMOS process. The entire transmitter including all inductors and filters is integrated in a single chip that gives the lowest cost solution to the end user. The only external components needed to make a complete RF system is a crystal and a resistor. Current consumption is around 10mA in transmit mode @ -5dBm. The total solution fits into a 4x4mm package. The nRF2401 is designed for wireless transmitter 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 nRF2402 transmitter is done via a standard serial interface. nRF2402 can replace IR and typical 27MHz communication in most applications. An innovative embedded feature in nRF2402 to reduce cost and current consumption is "ShockBurst" which uses an onboard FIFO to buffer up data and transmit in bursts, as well as dedicated on chip logic to compute the CRC checksum.
A "green" Pb (lead) free alternative
The nRF2402 is offered in a "green" lead free alternative - the nRF2402G - and confirms to current and future environmental standards. For more info, please go to Nordic Semiconductor Green/Pb Free Program.
