Microchip Technology and Marelli have introduced a new automotive display connectivity solution designed to support the growing shift towards software-defined vehicles. The joint solution enables graphics and video generated by a vehicle’s central computer to be transmitted directly to automotive displays using ASA Motion Link, an open standard for automotive video connectivity.
The demonstrator has been developed to help vehicle manufacturers simplify electronic architectures, improve sourcing flexibility and manage system costs while supporting the increasing use of centralized computing in modern vehicles. ASA Motion Link is an open standard for automotive video connectivity and serializer-deserializer communication. Developed by the Automotive SerDes Alliance, the technology supports secure and high-speed transmission of graphics and video between products from different technology providers.
Microchip, a founding member of the Automotive SerDes Alliance, has been working to promote open and interoperable connectivity standards for the automotive industry. The company has already demonstrated the use of ASA Motion Link technology in camera connectivity and is now extending its capabilities to automotive displays.
As vehicle systems move towards centralized computing, manufacturers require faster and more flexible communication between central computers and various display systems. In the joint demonstrator, graphics and video content generated by the central computer is processed and transmitted using Microchip’s VS7000 ASA Motion Link chipset over a standardized high-speed connection.
Marelli has developed the display-side integration of the technology. Its solution configures and optimizes the ASA Motion Link deserializer to decode video streams directly at the display. This enables the accurate delivery of camera feeds, navigation maps, infotainment graphics and vehicle control interfaces.
Kelei Shen, President of Marelli’s Electronics Business, said the move towards software-defined vehicles is increasing the need for open and scalable electronic systems. “Open standards can help accelerate innovation while giving vehicle manufacturers the flexibility and interoperability needed for future vehicle architectures,” Mr Shen said.
Kevin So, Vice President of Microchip’s Communications Business Unit, said open connectivity standards can reduce dependence on proprietary technologies and simplify system integration. The solution supports data rates of up to 16 Gbps and includes link-layer authentication and encryption. It also offers strong resistance to electromagnetic interference and lossless data transmission.
The technology includes Time Division Duplex functionality and simplified Forward Error Correction, helping improve efficiency and reduce power consumption. It also provides a path towards increasingly Ethernet-based vehicle architectures. The collaboration between Microchip and Marelli highlights the growing importance of open standards as vehicle makers develop more connected, software-driven and centrally managed vehicles.
Microchip Technology is widely recognized for its semiconductor, embedded systems, and timing solutions used across automotive, industrial, aerospace, communications, and consumer electronics applications. Through ongoing innovation in frequency control and precision timing technologies, the company aims to support next-generation electronic systems that demand higher performance, lower power consumption, and improved operational resilience.
