SPRUJ63A September 2022 – October 2023
The USB0 port of AM64x/AM243x is used for USB 2.0 interface. The USB signals are terminated to a uAB connector and supporting circuitry is included to allow the USB interface to be configured as either host or a self-powered slave device.
In the host mode, up to 500 mA, 5 V is supported for the slave device. A power switch is included that is controlled by DRV_VBUS signal from the AM64x/AM243x.
A 2x3 header (J23) is provided to install the 2-position ganged shunt to configure the port for host mode as shown in Figure 3-24. Place the shunt on pin no. 1 and 2 to enable bulk capacitance on VBUS and place the shunt on pin 5 and 6 to connect ID pin to ground.
