Single chip ultra low power wireless
Ultra low power wireless system-on-chip solution
The nRF24LE1 is a unique solution offering a complete ultra low power (ULP) wireless system-on-chip (SoC) solution. It integrates the industry best nRF24L01 2.4GHz transceiver core, an enhanced 8051 microcontroller, flash memory and a wide range of analog and digital peripherals. The 8-bit microcontroller is powerful enough to run both the RF protocol stack and the application layer, enabling a true single chip implementation of ULP wireless applications.
Optimized for ultra low power wireless
Advanced power management and on-chip peripherals
The nRF24LE1 is optimized to provide a single chip solution for ULP wireless applications. The combination of processing power, memory, low power oscillators, real-time counter, AES encryption accelerator, random generator, plus a range of power saving modes provides an ideal platform for implementation of RF Protocols. Benefits include tighter protocol 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.
Three package sizes for different applications
Same core but different package and I/O count
The nRF24LE1 comes in three different package variants:
- An ultra compact 4x4mm 24-pin QFN (7 generic I/O pins)
- A compact 5x5mm 32-pin QFN (15 generic I/O pins)
- A 7x7mm 48-pin QFN (31 generic I/O pins)
The 4x4mm 24-pin QFN with 7 generic I/O pins 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 with 15 generic I/O pins is ideal for medium I/O count applications such as wireless mice, remote controls and toys. The 7x7mm 48-pin QFN with 31 generic I/O pins is for high I/O count products like wireless keyboards.
