GENERAL DESCRIPTION
nRF9E5 is a true single chip system with fully integrated RF transceiver, 8051 compatible microcontroller and a 4 input 10bit 80ksps AD converter. The transceiver of the system supports all the features available in the nRF905 chip including Shockburst(TM), which automatically handles preamble, address and CRC. The circuit has embedded voltage regulators, which provides maximum noise immunity and allows operation on a single 1.9V to 3.6V supply. nRF9E5 is compatible with FCC standard CFR47 part 15 and ETSI EN 300 220-1.
