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 PVRs, to USB port replicators, USB to Ethernet adapters, PC docking
stations, and test instrumentation, the LAN9500A is targeted as a high-performance
and 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 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 on-board RJ45 and USB
Type-A connectors. The on-board 256x8 EEPROM is used to load the
EVB-LAN9500A-LC’s USB configuration parameters and MAC address.
LAN95xx software drivers are available for Windows
