1 Introduction

The LAN7500 is a high performance Hi-Speed USB 2.0 to 10/100/1000 Ethernet controller. With
applications ranging from embedded systems, set-top boxes, and PVR’s, to USB port replicators, USB
to Ethernet dongles and test instrumentation, the device is a high performance and cost competitive
USB to Ethernet connectivity solution.

The LAN7500 contains an integrated 10/100/1000 Ethernet MAC and PHY, Filtering Engine, USB PHY,
Hi-Speed USB 2.0 device controller, TAP controller, EEPROM controller, and a FIFO controller with a
total of 32 KB of internal packet buffering.

The internal USB 2.0 device controller and USB PHY are compliant with the USB 2.0 Hi-Speed
standard. The device implements Control, Interrupt, Bulk-in, and Bulk-out USB Endpoints.

The Ethernet controller supports auto-negotiation, auto-polarity correction, HP Auto-MDIX, and is
compliant with the IEEE 802.3, IEEE 802.3u, IEEE 802.3ab standards. ARP and NS offload is also
supported.

The EVB-LAN7500-LC is an Evaluation Board (EVB) that utilizes the LAN7500 to provide a fully
functional, bus-powered USB to Ethernet interface. The EVB-LAN7500-LC provides a fully integrated
Ethernet port and USB port via the onboard RJ45 and USB Type A connectors. The onboard 4K
EEPROM is used to load the EVB-LAN7500-LC’s USB configuration parameters and MAC address.

LAN7500 software drivers are available for Windows XP, Windows Vista, Mac OSX, Linux, and Win
CE. Additional manufacturing and diagnostic tools are available for debugging and external EEPROM
configuration.

A simplified block diagram of the EVB-LAN7500-LC can be seen in Figure 1.1.
