Toyota Adds Vellfire Car Model to Rollout of Microchip MOST50 Networking Devices in Toyota Infotainment Systems

CHANDLER, AZ -- Microchip Technology Inc. announces that its MOST50 Intelligent network Interface Controllers (INICs) are powering the infotainment systems of the new Toyota Vellfire executive-lounge vehicles. This is the latest deployment among a wide variety of the Toyota Motor Corporation's brands, which have been using MOST50 in their infotainment systems for more than a decade, including both volume and luxury vehicles. In the new Vellfire implementation, Toyota is once again using MOST® technology to ensure high-quality digital audio throughout the vehicle.

To date, more than 170 million 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 utilize Microchip's MOST50 INICs, which feature an Electrical Physical Layer (ePHY) that is optimized for use with Unshielded Twisted Pair (UTP) copper wire. The result is a system that can predictably and efficiently transport video, audio, packet and control data throughout the vehicle without time-synchronization 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 Toyota Vellfire emphasizes strength and luxury, and uses our MOST50 technology in its infotainment system to provide high-quality digital audio," said Dan Termer, vice president of Microchip's Automotive Information Systems Division. "Toyota has been using MOST technology for more than a decade, and Vellfire is the latest entrant into the market. MOST provides a flexible platform to develop feature-rich infotainment systems."

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 Advanced Driver Assistance (ADAS) systems, including a standard physical layer and a robust method for system management and control with superior reliability and Quality of Service (QoS). Using MOST technology also results in reduced weight for easier compliance with environmental regulations.
