3.4.2 USB Interfaces

The USB (Universal Serial Bus) is a hot-pluggable general-purpose high-speed I/O standard for computer peripherals. The standard defines connector types, cabling, and communication protocols for interconnecting a wide variety of electronic devices. The USB 2.0 specification defines data transfer rates as high as 480 Mbps ("high-speed USB"). A USB host bus connector uses four pins: a power supply pin (5V), a differential pair (D+ and D- pins) and a ground pin.

The SAMA7G54-EK board features three USB communication ports named USBA, USBB and USBC.
