1 Introduction
The LAN9500A is a high performance, small form factor solution for USB to 10/100 Ethernet port
bridging. With applications ranging from embedded systems, set-top boxes, and PVR’s, to USB port
replicators, USB to Ethernet adapters, PC docking stations, and test instrumentation, the LAN9500A
is targeted as a high performance, low cost USB/Ethernet connectivity solution.
The LAN9500A contains an integrated 10/100 Ethernet PHY, USB PHY, Hi-Speed USB 2.0 device
controller, 10/100 Ethernet MAC, TAP controller, EEPROM controller, and a FIFO controller with a total
of 30 KB of internal packet buffering. The LAN9500A complies with the IEEE 802.3 (full/half-duplex
10BASE-T and 100BASE-TX) Ethernet protocol and USB 2.0 specification, enabling compatibility with
industry standard Fast Ethernet and USB 2.0 applications.
The EVB-LAN9500A-LC is an Evaluation Board (EVB) that utilizes the LAN9500A to provide a fully
functional, bus-powered USB to Ethernet interface. The EVB-LAN9500A-LC provides fully integrated
Ethernet and USB ports via the onboard RJ45 and USB Type A connectors. The onboard 256x8
EEPROM is used to load the EVB-LAN9500A-LC’s USB configuration parameters and MAC address.
LAN9500A software drivers are available for Windows XP, Windows Vista, Mac OS X, Linux, and
Windows CE. Additional manufacturing and diagnostic tools are available for debugging and external
EEPROM configuration. For complete details, refer to the “LAN9500A Software User Manual”.
A simplified block diagram of the EVB-LAN9500A-LC can be seen in Figure 1.1.
