The nRF9E5 is a truly integrated RF transceiver, 8051 compatible microcontroller and a 4 input 10bit 80ksps AD converter.
The nRF9ES integrates a fully‑featured RF transceiver, an 8051‑compatible microcontroller, and a 4‑input 10‑bit ADC on a 5 × 5 mm QFN package. It operates from a single 1.9 V to 3.6 V supply and offers features such as ShockBurst™ protocol handling, carrier‑detect, and adjustable output power up to 10 dBm.
The datasheet provides electrical specifications, pin assignments, clock options, and detailed descriptions of the ADC, power‑management modes, and radio subsystem. It also includes application examples for industrial sensors, remote‑control, alarm systems, and telemetry.
