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, 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-MII is an Evaluation Board (EVB) that utilizes the LAN9500A to provide a fully functional, USB to Ethernet interface. The EVB-LAN9500A-MII provides fully integrated Ethernet and USB ports via the onboard RJ45 and USB Type B connectors. The EVB-LAN9500A-MII can be configured for bus- or self-powered operation and supports internal and external PHY modes. An external PHY may be connected via the onboard 40-pin female MII connector. The onboard 256x8 EEPROM is used to load the EVB-LAN9500A-MIIs 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-MII can be seen in Figure 1.1.
