Microchip's LAN89730 was specifically designed to provide a high-performance, low-cost USB to 10/100 Ethernet connectivity solution with a Hi-Speed Inter-Chip (HSIC) interface for automotive applications. Many high-performance mobile processor include an HSIC interface to reduce pin count and power, and often do not include an Ethernet interface. The LAN89730 provides a convenient way to connect such processors to an Ethernet network. Taking advantage of the broad availability of existing USB drivers and software, Microchip's proprietary HSIC technology incorporates a 2-pin digital bus that enables the use of USB as a low-power, chip-to-chip interconnect at speeds up to 480 Mbps. The internal device controller is USB 2.0-compliant and the HSIC interface is HSIC USB Electrical Specification Revision 1.0-compliant. The device 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 25MHz crystal for both USB and Ethernet connectivity – without the need for additional components when adding USB hubs. Additional Features
Single-chip USB 2.0 to 10/100 Ethernet controller for Automotive applications
NetDetachTM for reduced system power consumption
EEPROM-less operation - reduced BOM costs
UniClockTM Technology enables single 25 MHz crystal for both USB and Ethernet
Driver support for Win 8/7/XP/Vista, Linux, CE, MAC
Automotive AEC-Q100 qualified, Grade 3 (-40° to 85°C) temperature ranges.
Ideal for bridging Telematic modem to in-vehicle Ethernet network
Ideal for Head Unit SoC to in-vehicle Ethernet networks
