New MOST® Technology Intelligent Network Interface Controller Enables Daisy-Chain Communications in Automotive Applications
Using Microchip’s OS81119 INIC allows customers to simplify the network architecture of automotive in-vehicle infotainment systems by using integrated coaxial physical layer (cPHY), optical physical layer (oPHY), daisy-chain topologies or creative hybrid combinations. Customers currently using MOST150 systems can also rapidly migrate to new topologies or daisy-chain additional nodes with little hardware and software redesign.
“This is the first time customers can create a MOST150 network using a daisy-chain configuration,” said Dan Termer, vice president of Microchip’s Automotive Information Systems business unit. “MOST networks are a proven standard used in more than 200 car models across all major OEMs. Continuous innovation, as shown with this new device, now makes MOST technology even more cost-effective.”
Besides an integrated cPHY, a USB 2.0 high-speed user interface is also part of the OS81119 INIC. This integration further reduces system component count, driving down overall costs. Time to market can be improved when using the USB standard and corresponding standardized MOST Linux® Driver. Additionally, utilizing an open-source Linux operating system and driver for the OS81119 helps customers reduce costs. By using the standard Application Programming Interfaces (APIs), customers can also minimize the risk of application issues.
MOST technology is the choice of many automobile manufacturers and tier one suppliers for in-vehicle networking. It specifically targets infotainment and telematics applications such as smart antennas, head units, amplifiers, digital clusters, rear seat entertainment, Advanced Driver-Assistance Systems (ADAS), driver/passenger information systems and public transportation infotainment and information systems.
