Ethernet Transceiver Cuts Repair Time With High-Speed Automotive Interface

The LAN88710 MII/RMII 10/100 Ethernet transceiver is designed specifically to meet the high-reliability standards required by automotive applications such as on-board diagnostics or fast software download interfaces for central gateway and telematics modules, navigation systems, radio head units, and connectivity devices. When used within today's complex vehicle electrical systems, the TrueAuto LAN88710 transceiver can help diagnose issues faster and lower software maintenance time so repairs are completed more quickly and cost less. It provides a simple, digital interface via the MII standard (IEEE 802.3u) to a typical MAC layer integrated within an embedded microcontroller. Built into an embedded device within the car, the chip can function as a network branch to the outside world, connecting the car to a personal computer, diagnostic tool, or to a complex Ethernet network in the repair shop. Comprehensive flexPWR technology provides a flexible power-management architecture and power savings of up to 40 percent compared to similar devices. The LVCMOS variable I/O voltage range is +1.6 V to +3.6 V, and the integrated 1.2-V regulator has a disable feature. The LAN88710 comes in a 32-pin QFN lead-free RoHS compliant package measuring 5 mm x 5 mm x 0.9 mm. Samples are available today. SMSC, Hauppauge, NY. (631) 435-6000.
