PRODUCT SUmmaRy

Ultra low power, compact and low cost 2.4GHz transceiver

The nRF24L01+

The nRF24L01+ is a unique wireless solution for compact, battery operated

applications with stringent requirements on battery lifetime and cost. The

transceiver operates in the license free worldwide 2.4GHz ISM band.

It is specifically designed for two types of application: PC peripherals and

ultra low power applications such as sports and wellness sensors. For PC

peripherals such as wireless mice, keyboards and media center remotes

it enables high performance and long battery life at a low solution cost.

For sensor applications the ultra low power consumption and advanced

power management enables battery lifetimes up to several years on

a coin cell battery.

Smooth transition from nRF24L01

Improved co-existence performance and longer range

The nRF24L01+ is mechanically, functional and electrical drop in compatible

with the nRF24L01. In addition it offers significant improvements on co-

existence performance with wide band inference sources like WiFi compared

to nRF24L01. It also adds a 250 kbps air-data rate mode offering -94dBm

sensitivity for longer range operation.

Compact, highly integrated low cost solution

Compact 4x4mm package, low cost external BOm

The nRF24L01+ integrates a complete 2.4GHz RF transceiver, an RF

synthesizer, and full baseband logic including the unique Enhanced Shock-

Burst™ hardware link layer, advanced power management and a high-speed

SPI for the host controller interface. No external loop filters, resonators or

VCO varactor diodes are required, only a low cost ±60ppm 16MHz crystal,

matching circuitry and the antenna.

Ultra low power consumption

a unique combination of high air data rate and advanced

power management

The nRF24L01+ has a unique combination of four features that enable the

implementation of ultra-low power wireless connectivity:

• Sub 14mA TX and RX active currents that permit coin-cell battery operation

• Advanced power management with power saving idle modes combined

• High 2 Mbps on-air data rate that allows the transceiver to minimize

• Enhanced ShockBurst™ link layer minimizes processing load on the
