Seoul, May 29, 2015 – Microchip Technology (Korea Representative: Byung-Don Han), a global leader in microcontroller, mixed-signal, analog, and Flash-IP solutions, announced that Volvo Car Group’s new Volvo XC90 model has successfully migrated seamlessly from MOST25 to the latest MOST150 standard using Microchip’s OS81110 Intelligent Network Interface Controller (INIC). Volvo Car Group, which has used Microchip’s MOST25 INIC for several years, sought to build a modern infotainment system equipped with Ethernet packet transmission capabilities. To this end, they adopted MOST150, the only standard that provides a physical layer with proven performance for in-vehicle Ethernet packet transmission as well as a wide range of functions. Additionally, the fact that MOST150 adheres to the IEEE 802.3 Ethernet specification was a major factor in the selection of MOST150.

Since 2001, more than 170 million MOST interface controllers have been adopted across 184 vehicle models. All major automotive manufacturers, including Volvo, have successfully implemented MOST technology in their multi-node infotainment networking systems, providing low-risk, comprehensive system solutions based on years of proven performance. The MOST150 standard perfectly meets Volvo’s requirements for connectivity and bandwidth. In addition, this latest version of MOST technology predictably and efficiently transmits video, audio, packet, and control data from the entire vehicle without a time synchronization protocol, and implements a system that minimizes processor overhead in the main infotainment control unit processor by utilizing a dedicated channel.

"We are very pleased that Volvo has become the fourth automaker to adopt MOST150 technology for its high-speed infotainment network," said Dan Termer, Vice President of Microchip's Automotive Business Unit. "This demonstrates that the migration to MOST150 by OEMs is spreading. Demand for the MOST technology standard is surging, and customers who have already experienced it are applying MOST150 to their next-generation car models."

The MOST150 also provides 150 Mbps performance and proven Electromagnetic Compatibility (EMC) characteristics. This EMC performance is combined with the optical-physical layer utilized in the all-new Volvo XC90 models to demonstrate superior performance. All MOST INICs provide industry-standard hardware interfaces to processors and peripherals, enabling efficient routing of audio, video, and packet data and significantly simplifying module design. End users can instantly access automotive infotainment systems with the MOST INIC's ultra-high-speed network startup capabilities.

The MOST Corporation standard provides automotive OEMs and Tier 1 suppliers with proven performance and suitable support for the definition and implementation of high-bandwidth infotainment and Advanced Driver Assistance systems (ADAS). This includes standard physical layers and highly reliable techniques for system management and control through superior stability and Quality of Service (QoS). In addition, using MOST technology reduces the weight of the vehicle body, making it easier to meet environmental regulations.
