nRF24LU1+ Ultra Low Power Wireless System-on-Chip USB Solution

A single chip solution with the nRF24LU1
The nRF24LU1 is a unique single chip solution enabling ultra compact USB dongles for wireless peripherals. By integrating an USB 2.0 compliant device controller, 8 bit application microcontroller and a nRF24L01 compatible 2.4GHz RF Transceiver it supports a wide range of application including PC peripherals, sports accessories and game peripherals. With air data rate of up to 2 Mbps combined with full speed USB, supporting up to 12 Mbps, the nRF24LU1 meets all the requirements of applications with stringent performance requirements such as wireless mouse, game controllers and media center remote controls with displays.

Highly integrated solution
Compact 5x5mm package, low cost external BOM
In addition to the main blocks the nRF24LU1 integrates other critical functionality, saving cost and board space. Internal memory removes the need for an external EEPROM. An internal voltage regulator enables the chip to be powered directly from the USB bus; it does not require an external voltage regulator. With a fully integrated RF synthesizer and PLL for the USB no external loop filters, resonators or VCO varactor diodes is required. Only 1 low cost ±60ppm 16MHz crystal plus passives for ESD protection, decoupling, antenna matching circuitry is required. nRF24LU1 enables true single chip USB dongles.

nRFgo a complete development platform
For firmware and hardware engineers
The nRF24LU1 is supported by a complete development platform enabling designers to easily develop hardware and firmware for the chip. The platform comprises two key elements: the nRFgo Starter Kit and the nRF24LU1 Development Kit. Both are required to get started with nRF24LU1 development.

The nRFgo Starter Kit provides a generic development platform for all nRF devices providing motherboards with sockets for the nRFgo development kit modules as well as the nRFgo Studio evaluation and management PC application. The nRF24LU1 Development Kit comes in only one version, fitted with nRF24LU1P-F32Q32 (32 kbytes flash memory) devices. The kit include nRFgo compatible nRF24LU1 radio modules, a production ready USB dongle, complete Software Development Kit (SDK) and the nRFprobe hardware debug utility.
