Product Summary

The NRF9E5 B 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 NRF9E5 B chip including Shockburst, 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. The applications of the NRF9E5 B include Sports and leisure, equipment, Alarm and security system, Industrial sensors, Remote control, Surveillance, Automotive, Telemetry, Keyless entry, Toys.
