The nRF24LE1 is a highly integrated ultra low power 2.4GHz RF System-on-Chip (SoC) for 2.4GHz ISM (Industrial, Scientific and Medical) band operation. It includes a 2.4GHz RF transceiver core, an 8-bit CPU, and embedded Flash memory. By offering a peak RX/TX current lower than 14mA, a sub-μA power down mode, advanced power management, and 1.9 to 3.6V supply range, the nRF24LE1 provides a true ultra low power solution that enables months to years of battery lifetime when running from regular coin cells or AA/AAA batteries. Finally, a rich set of on-chip analog and digital peripherals makes the nRF24LE1 a flexible, single chip solution for a wide range of applications including PC peripherals, game controllers, remote controls, sports/fitness/healthcare sensors, and toys.
The nRF24LE1 integrates an nRF24L01+ 2.4GHz RF transceiver core, enhanced 16MHz 8-bit 8051 compatible CPU, 1kB + 256B RAM, 16kB embedded Flash, and a wide range of system peripherals including a hardware AES accelerator, 16MHz and 32kHz RC oscillators, ultra low power 32kHz crystal oscillator, 12-bit ADC and SPI, 2-wire and UART serial interfaces.
The nRF24LE1 is available in 3 package options:
4 x 4mm 24-pin QFN with 7 generic I/O pins
5 x 5mm 32-pin QFN with 15 generic I/O pins
7 x 7mm 48-pin QFN with 31 generic I/O pins
The 4×4mm 24 pin QFN is ideal for low I/O count applications where small size is key. Examples include wearable sports sensors and watches. The 5×5mm 32 pin QFN is ideal for medium I/O count applications such as wireless mouse, remote controls and toys. The 7×7mm 48 pin QFN is designed for high I/O count products like wireless keyboards.
