The LAN9500/LAN9500i is a high performance Hi-Speed USB 2.0 to 10/100 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 LAN9500/LAN9500i is a high performance and cost competitive USB to Ethernet connectivity solution.

The LAN9500/LAN9500i 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 internal USB 2.0 device controller and USB PHY are compliant with the USB 2.0 Hi-Speed standard. The LAN9500/LAN9500i 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 and IEEE 802.3u standards. An external MII interface provides support for an external Fast Ethernet PHY, HomePNA, and HomePlug functionality.

Multiple power management features are provided, including various low power modes and "Magic Packet", "Wake On LAN", and "Link Status Change" wake events. These wake events can be programmed to initiate a USB remote wakeup.

An internal EEPROM controller exists to load various USB configuration information and the device MAC address. The integrated IEEE 1149.1 compliant TAP controller provides boundary scan via JTAG.
