The Nordic 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.
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.
