Low-power automotive ethernet transceiver

  • 10-Jul-2012 03:14 EDT

SMSC’s TrueAuto LAN88730 MII/RMII 10/100 low-power automotive ethernet transceiver is designed specifically to meet the high reliability requirements of automotive applications such as onboard diagnostics or fast software download interfaces for central gateway and telematics modules, navigation systems, radio head units, and connectivity devices. According to SMSC, the transceiver delivers increased access speed for diagnostics and software downloads when compared with the more traditional interfaces used by carmakers to date. It offers a simple, digital interface via MII (IEEE 802.3u) to a standard MAC (media access control) layer integrated in 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 a complex ethernet network in the repair shop.
