This document describes a product with a 2.4GHz RF transceiver, 8051 compatible microcontroller, and 9 input 10-bit ADC. It supports applications such as wireless gamepads, wireless headsets, wireless keyboards, wireless mice, intelligent sports equipment, industrial sensors, PC peripherals, phone peripherals, tags, alarms, and remote control.
The nRF24E1 is a 2.4 GHz RF transceiver that integrates an 8051‑compatible microcontroller and a 9‑input, 10‑bit ADC. It operates from a single supply (1.9 V‑3.6 V) and supports proprietary modes such as ShockBurst™ and DuoCeiver™ for wireless gamepads, headsets, keyboards, mice, toys, sensors and other peripherals.
This handbook contains a general description, architectural overview, pin‑out diagrams, electrical specifications, power‑saving modes, and application examples. It also includes quick reference data, block diagrams, glossary of terms, and detailed information on the ADC, PWM, interrupts, watchdog, and RF performance.
