Status: In Production Consider: LAN89730
Microchip's LAN89530 was specifically designed to provide a high performance, low-cost USB to 10/100 Ethernet connectivity solution with a Hi-Speed USB interface for Automotive applicaitons. The internal USB device controller is USB 2.0-compliant and implements Control, Interrupt and Bulk-in and Bulk-out USB endpoints. Microchip's UniClock™ technology simplifies the clocking scheme and reduces system BOM costs by using a single 25 MHz crystal for both USB and Ethernet connectivity - without the need for additional components when adding USB hubs. Applications well-suited for the LAN89530 include a diagnostic interface for dealership service bay, a fast software download interface with an OBD connector and an in-vehicle engineering development interface, among others. The LAN89530 also supports auto-negotiation, auto-polarity correction, HP Auto-MDIX and is compliant with IEEE802.3 and 802.3u standards. An external MII provides support for an external PHY which enables HomePNA® or HomePlug® functionality. Multiple power management features are provided, including various low power modes, as well as Magic Packet, Wake-on-LAN and Link Status Change wake events. These events can be programmed to initiate a remote USB wakeup. A PCI-like PME wake is also supported when the USB host controller is disabled.
