The USB OTG dual-role controller can operate either as a function controller for a USB peripheral or as the host/peripheral in point-to-point or multipoint communications with other functions. The integrated USB 2.0 PHY provides one-port operation at low speed (1.5 Mbps), full speed (12 Mbps), and high speed (480 Mbps). The VLYNQ serial interface is a low pin count, high-speed, point-to-point interface.The device is fully compliant with Universal Serial Bus Specification Revision 2.0 and On-the-Go Supplement to the USB Specification Revision 1.3.
