AM64x / AM243x processor supports 1 x USB 3.1 Dual-Role Device (DRD) Subsystem. These Ports are configurable as USB host (SuperSpeed Gen 1 (5 Gbps), High-speed (480 Mbps), Full-speed (12 Mbps), and Low-speed (1.5 Mbps)), USB device (High-speed (480 Mbps), and Full-speed (12 Mbps)), or USB Dual-Role device.
Follow USB VBUS Design Guidelines section of the device-specific data sheet for scaling the VBUS voltage.
VBUS voltage is required to be connected when the device is configured in device mode. VBUS connection is optional in host mode.
A power switch with OC (over current) indication connected to an processor GPIO is recommended when the USB interface is configured as host. The DRVVBUS drives the power switch.
For USB connections and On-The-Go feature support, see the device-specific TRM.
For more details, refer the High-speed Serial Interfaces section in the Peripherals chapter of the device-specific TRM.
