1 Introduction

The LAN9512 is a high performance, Hi-Speed USB 2.0 hub with a 10/100 Ethernet controller. 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 LAN9512’s 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
