Single-chip ANT solution equipped with USB 2.0

Nordic Semiconductor ASA has released nRF24AP2-USB single-chip ANT solution with USB interface enabling compact, low-cost ANT USB dongles for wireless sport, fitness and health monitoring products.

The third product in its nRF24AP2 ANT family, the nRF24AP2-USB provides the same advanced feature set as Nordic's existing eight-channel nRF24AP2-8CH ultralow power (ULP) wireless solution, but exchanges the latter's UART interface for a Full-Speed USB 2.0 compliant host interface. This makes the nRF24AP2-USB suitable for both compact ANT USB dongles and embedded systems where a USB host interface is preferred.

The nRF24AP2-USB comes in a compact 5mm x 5mm QFN package and integrates a Nordic 2.4GHz nRF24L01+ transceiver core, eight-channel ANT protocol stack, Full-Speed USB 2.0 device controller, and 4V to 5.25V linear voltage regulator that allows the chip to be powered directly from a USB bus port.

Supporting development tools for the nRF24AP2-USB include the production-ready nRF6910 nRFready ANT USB Dongle reference design and development platform, plus ANT libraries and drivers for both Windows and Mac OS X.
