The LAN9512 contains an integrated USB 2.0 hub, two integrated downstream USB 2.0 PHYs, an integrated upstream USB 2.0 PHY, a 10/100 Ethernet PHY, a 10/100 Ethernet controller, a TAP controller, and an EEPROM controller. The EVB9512 is an Evaluation Board (EVB) that utilizes the LAN9512 to provide a two port USB 2.0 hub with an integrated 10/100 Ethernet controller. The EVB9512 provides USB connectivity via one type B upstream USB connector and two type A downstream USB connectors. An RJ-45 integrated magnetics Ethernet jack with link/activity LEDs provides 10/100 Ethernet connectivity. The EVB9512 supports both bus-powered and self-powered modes of operation. The EVB9512 includes a 512x8 Microwire EEPROM that may be used to automatically load USB descriptors, USB device configuration, and the MAC address upon reset. A GPIO header provides access to the LAN9512s general purpose I/O signals. For debugging purposes, the internal LAN9512 TAP controller is accessible via the included JTAG header. A simplified block diagram of the EVB9512 can be seen in Figure 1.1.
