nRF24LE1 Preliminary Product Specification
The nRF24LE1 is a member of the low-cost, high-performance nRF24 family of intelligent 2.4 GHz RF
Transceivers with embedded microcontrollers. The nRF24LE1 is optimized to provide a single chip solu-
tion for ULP wireless applications. The combination of processing power, memory, low power oscillators,
real-time counter, AES encryption accelerator, random generator and a range of power saving modes pro-
vides an ideal platform for implementation of RF protocols. Benefits of using nRF24LE1 include tighter pro-
tocol timing, security, lower power consumption and improved co-existence performance. For the
application layer the nRF24LE1 offers a rich set of peripherals including: SPI, 2-wire, UART, 6 to 12 bit
ADC, PWM and an ultra low power analog comparator for voltage level system wake-up.
The nRF24LE1 comes in three different package variants:
The 4x4mm 24 pin QFN is ideal for low I/O count applications where small size is key. Examples include
wearable sports sensors and watches. The 5x5mm 32 pin QFN is ideal for medium I/O count applications
such as wireless mouse, remote controls and toys. The 7x7mm 48 pin QFN is designed for high I/O count
products like wireless keyboards.
