Microchip announced that the Volvo Car Group has used Microchip ’s OS81110 Intelligent Network Interface Controller (INIC) to migrate its new Volvo XC90 model from MOST25 to the latest MOST150 standard. After using Microchip ’s MOST25 INIC for many years, Volvo Car Corporation needed to make its latest infotainment system capable of carrying Ethernet packets. MOST150 is a natural choice, because in addition to all its other functions, it is the first and only standard that provides a proven, physical layer that can be used for automotive Ethernet packet transmission within the car-and it complies with IEEE 802.3 The company stated that the Ethernet specification.
So far, since 2001, more than 170 million MOST interface controllers have been installed in 184 car models. Volvo Car Corporation and all major car manufacturers have successfully implemented MOST technology in their multi-node infotainment network system for many years because it provides proven technology. , A low-risk system-wide solution. The MOST150 standard meets the connectivity and bandwidth requirements of Volvo Cars. The latest MOST technology version uses a dedicated channel to minimize the processor overhead in the main infotainment control unit processor, so that it can continue to predictably and efficiently transmit video and audio throughout the vehicle without a time synchronization protocol , Data packets and control data.
Dan Termer, vice president of Microchip Motors, said: "We are pleased that Volvo Cars has become the fourth car manufacturer to adopt MOST150 technology as its high-speed infotainment network." "This is another example of OEMs moving to MOST150. They are at MOST Their experience in technical standards and growing demand have prompted them to choose MOST150 as their new and future car model. "
MOST150 also provides 150 Mbps performance and proven electromagnetic compatibility (EMC) behavior. This EMC performance is particularly good when combined with the optical physical layer used in the new Volvo XC90 model. All MOST INICs provide industry-standard hardware interfaces to processors and peripherals to efficiently route flows, packets, and control data, which greatly simplifies module design. Due to MOST INIC's ultra-fast network startup behavior, end users can immediately access the vehicle's infotainment system.
The MOST collaborative standard enables automotive OEMs and their Tier 1 suppliers to use a proven method to define and implement high-bandwidth infotainment and advanced driver assistance (ADAS) systems, including the standard physical layer and Reliable method of system management and management. With excellent reliability and quality of service (QoS) control. The company said that using MOST technology can also reduce weight, making it easier to comply with environmental regulations.
