The T2080RDB-PC systems have two integrated USB 2.0 controllers, that allow direct connection to USB ports with appropriate
protection circuitry and power supplies.
The board features are:
• High speed (480 Mbit/s), full-speed (12 Mbit/s), and low-speed (1.5 Mbit/s) operation
• Host mode
• Dual stacked Type A connection
The USB ports connect to a standard Type A connector (USB1 and USB2) for compatibility with most USB peripherals.
Power for the ports is provided by a MIC2506YM, which supplies 5 V at up to 1 A per port. The power enable and power-fault-detect
pins are connected directly to the T2080 for individual port management.
The image below shows how the USB connectivity is implemented on the T2080RDB-PC.
