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 perform-
ance. For the application layer the nRF24LE1 offers a rich set of peripher-
als including: SPI, 2-wire, UART, 6 to 12-bit ADC, PWM, and an ultra low
power analog comparator for voltage level system wake-up.
• 2-channel PWM
• Programmable resolution ADC: 6, 8, 10, or 12-bits
• Random Number Generator based on thermal noise
• Supports the Nordic nRFProbe hardware debugger
• Programmable generic I/O pins
• Three package options:
4x4mm 24-pin QFN (7 Generic I/O pins)
5x5mm 32-pin QFN (15 Generic I/O pins)
7x7mm 48-pin QFN (31 Generic I/O pins)
Three package sizes for different applications
Same core but different package and I/O count
APPLICATIONS
• PC peripherals – mice, keyboards and remotes
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)
• Gaming controllers
• RF remote controls for consumer electronics devices such as set-top boxes,
media players and TVs
• 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.
• Sports and healthcare sensors
• Sport watches, bike computers, and gym equipment
• Remote controlled toys
• Active RFID
