Microchip Technology has announced that AUDI AG is networking the Audi virtual cockpit system in its new high-class Q7 SUV Models using MOST technology, following a similar deployment in its TT Coupe Models. Specifically, Audi is utilising Microchip’s OS81110 and OS81118 MOST150 Intelligent Network Interface Controllers (INICs), which provide 150Mb/s 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 SoC processor.

To date, more than 170m MOST interface controllers have been installed in 184 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 to 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.

“We are very grateful that Audi has once again adopted MOST150 Technology, this time in its new Q7 SUV model,” said Dan Termer, Vice President, Automotive, Microchip.

MOST150 also provides 150Mb/s performance and proven EMC behaviour. 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 behaviour.
