General Motors using Microchip’s automotive infotainment networking solution

Published: June 22, 2016 | Arizona, United States

General Motors (GM) is using Microchip’s Media Oriented Systems Transport (MOST®) Intelligent Network Interface Controllers (INICs) to manage the infotainment system networking functions in their global compact car platform.  Cars that are going to use this includes, Chevy Cruze, Chevy Volt, Opel Astra, Buick Excelle and Buick Verano. In addition to these compact cars, the synchronous, flexible, and cost-effective MOST networking technology has also been implemented in GM mid-size, full-size, performance, cross-over and SUV, truck, and luxury platforms across all vehicle brands.

MOST is a networking system standard for 30 global car maker brands and over 204 vehicle models. MOST-based vehicles are now being manufactured worldwide, including North America, Asia and Europe. It enables the car manufacturers to offer system and feature set flexibility for current and future automotive infotainment applications. This also helps reduce the wiring harness weight for easier compliance with environmental regulations.


GM’s infotainment network utilizes Microchip’s MOST50 INIC with an electrical Physical Layer (ePHY), which is optimized for use with unshielded twisted pair (UTP) copper wire, and meets the automotive industries stringent EMC standards.

Dan Termer, vice president of Microchip’s Automotive Information Systems Division, said:

The launch of MOST technology in GM’s compact cars solidifies the global acceptance of Microchip’s MOST system solutions in a wide variety of vehicle platforms, and proves its value beyond the luxury car brands. Car makers can offer networking features cost-effectively because of MOST technology’s inherent synchronous nature and intelligent use of network bandwidth. Another advantage is Microchip’s excellent systems-based applications engineering support throughout the car makers’ platform development process.
