●The LAN7500-ABZJ is a Hi-Speed USB 2.0 to 10/100/1000 Ethernet Controller 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 32kB 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. 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 an USB remote wakeup.
