Ethernet transceiver features high-speed automotive interface

SMSC has launched the LAN88710 MII/RMII 10/100 Ethernet transceiver, its second TrueAuto Ethernet solution. This device is designed to meet the 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 complex vehicle electrical systems, which are packed with user content, the transceiver can diagnose issues faster and can lower software maintenance time. The device provides a 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. The features of the transceiver include: single-chip Ethernet physical layer transceiver; flexPWR technology; LVCMOS variable I/O voltage range from +1.6V to +3.6V; integrated 1.2V regulator with disable feature; HP auto-MDIX support; 32pin QFN lead-free RoHS compliant package.
