The board provides 2-port USB 2.0 host interfaces using the SMSC USB3300 controller and 2-port
hub controller. A SMSC USB3300 device in a 32-pin QFN package device is used to interface to a
SMSC USB2512B. This device supports UTMI+ Low Pin Interface (ULPI) to communicate to USB
2.0 controller in HPS. By connecting the ID pin of USB3300 to ground, the PHY operates in Host
mode. When operating in Host mode, the interface will supply the power to the device through the
2-port USB type-A interface.
Figure 3-34
shows the schematic diagram of the USB circuitry; the
pin assignments for the associated interface are listed in
Table 3-33
