Microchip Technology, a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, announced that Audi is using MOST technology to network the high-end Audi virtual cockpit system in the latest model year of its best-selling A4 Sedans. This follows a similar deployment in its Q7 SUV and TT Coupe models. Specifically, Audi is utilizing Microchip’s OS81110 and OS81118 MOST150 Intelligent Network Interface Controllers (INICs), which provide 150 Mbps performance and support all MOST network data types.
The OS81118 also includes a High Speed USB 2.0 interface (PHY/HSIC), to seamlessly connect with the virtual cockpit’s System-on-Chip processor.

To date, approximately 200 million MOST interface controllers have been installed in 194 car models since 2001. Audi 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. The MOST150 standard also provides Ethernet or Internet-protocol networking capabilities.
This latest version of MOST technology continues predictably and efficiently to 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.
MOST150 also provides 150 Mbps performance and proven electromagnetic-compatibility (EMC) behavior. All MOST INICs offer industry-standard hardware interfaces to processor and peripheral devices for the efficient routing of streaming, packet and control 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 behavior.
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 reduces weight for easier compliance with environmental regulations.
