nRF24E1

2.4GHz RF System-on-Chip (SoC)
Not recommended
Overview

Description

This product is not recommended for new designs. Nordic recommends the nRF24LE1 or nRF24LE1 OTP for new designs.

The Nordic nRF24E1 is a low power, 2.4GHz RF SoC for the 2.4GHz ISM (Industrial, Scientific and Medical) band. It includes a 2.4GHz RF transceiver core, 8-bit CPU and RAM code memory. With its rich set of on-chip analog and digital peripherals the nRF24E1 is an ideal low cost, flexible, single chip, ultra low power (ULP) solution for a range of applications including PC peripherals, game controllers, remote controls, wireless sports/fitness/healthcare sensors, and toys.

The nRF24E1 integrates an nRF2401 2.4GHz RF transceiver core, 8-bit 8051 compatible CPU, 256B RAM, 4kB RAM code memory, boot loader, and a wide range of system peripherals including a 10-bit ADC and SPI, and UART serial interfaces.

The nRF24E1 is available in a 6 x 6mm 36-pin QFN with 10 generic I/O pins.
