Toyota continues rollout of Microchip MOST50 networking devices

To date, more than 170m MOST devices have been installed in 191 car models since 2001. Toyota and all major carmakers have for many years successfully implemented MOST technology in their multi-node infotainment networking systems, as it provides a field-proven, low-risk, whole-system solution. Toyota’s networks utilise Microchip’s MOST50 INICs, which feature an Electrical Physical Layer that is optimised for use with Unshielded Twisted Pair copper wire. The result is a system that can predictably and efficiently transport video, audio, packet and control data throughout the vehicle without time-synchronisation protocols, using dedicated channels for minimal processor overhead in the main infotainment control unit processors. The remote-connection-management and remote-control capabilities of all MOST INICs enable further options, including the ability to build slim (processor-less) network nodes. MOST INICs also provide industry-standard hardware interfaces to processor and peripheral devices for the efficient routing of audio, video and packet data, which greatly simplifies module designs. End users can immediately access the vehicle’s infotainment system, due to the MOST INIC’s ultra-fast network startup feature.

The MOST Cooperation standards enable automotive OEMs and their Tier 1 suppliers with a proven and well-supported methodology for defining and implementing high-bandwidth infotainment and ADAS systems, including a standard physical layer and a robust method for system management and control with superior reliability and QoS. Using MOST technology also results in reduced weight for easier compliance with environmental regulations.

“We are excited about Toyota’s latest implementation of our MOST50 technology in its Alphard infotainment system,” said Dan Termer, Vice President, Automotive Information Systems Division, Microchip Technology. “Toyota has been using MOST technology for several years, and they are now using it to achieve high-quality digital audio in the Alphard, which is a key differentiator in the executive-lounge class of vehicles.”
