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
ShockburstTM, 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.
