A single chip solution with the nRF24LU1+ OTP
The nRF24LU1+ OTP is a unique single chip solution for compact USB dongles for entry level 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+ OTP meets 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+ OTP integrates other critical functionality, saving cost and board space. 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 are required.

Only 1 low cost ±60ppm 16MHz crystal plus passives for ESD protection, decoupling, antenna matching circuitry is required. nRF24LU1+ OTP, enables true single chip USB dongles (depicted dongle is part of the nRF24LU1+ development kit).

A complete development platform
For firmware and hardware engineers The nRF24LU1+ OTP is supported by a complete development platform enabling designers to easily develop hardware and firmware for the chip. The platform comprises three key elements: the nRFgo Starter Kit, the nRF24LU1+ Development Kit (flash version) and the nRFgo Flash/OTP Programming Adapter Kit.

The development kit for the nRF24LU1+ OTP is the same as for the nRF24LU1+ (flash version), documentation is available on how to develop firmware on the flash version that works on the nRF24LU1+ OTP. The nRFgo Flash/OTP Programming Adapter Kit is a plug-in for the nRFgo Starter Kit that enables both programming of blank un-mounted and mounted nRF24LU1+ OTP parts.
