American chipmaker Microchip Technology and Korean mobility company Hyundai Motor Group have agreed to explore the adoption of advanced in-vehicle network solutions based on the 10BASE-T1S Single Pair Ethernet (SPE) Technology.

The collaboration will focus on Hyundai Motor Group integrating Microchip’s 10BASE-T1S solutions into its future vehicle platforms. Specifically, this will cover in high-growth areas such as electric vehicles, autonomous driving, and smart mobility.

Offers Greater Efficiency, Cost-Effectiveness

The rapid advancement of Advanced Driver-Assistance Systems (ADAS) and connected vehicle features is driving the need for robust, high-performance in-vehicle networks.

10BASE-T1S is the latest technology used to expand Ethernet to the edge of Operational Technology (OT) and Information Technology (IT) networks. Moreover, it provides a 10Mbps multidrop transmission medium that can include up to at least eight transceiver nodes, which can connect to a common mixing segment of up to 25m.

In addition, 10BASE-T1S technology supports multi-drop Ethernet communication over a single twisted pair. Therefore, extending in-vehicle networking to the edge—connecting devices, actuators and sensors with greater efficiency and cost-effectiveness.

SPE serves as a foundational technology for modern automotive architectures, enabling seamless connectivity across systems. By reducing the need for bridging between multiple standard and proprietary communication buses, SPE significantly simplifies wiring, lowers system costs and streamlines network integration.

Matthias Kaestner, corporate vice president of Microchip’s automotive, datacenter and networking business, said, “Our comprehensive portfolio of Single Pair Ethernet hardware and software solutions enables customers to reduce cost, risk, and time to market…Our collaboration with Hyundai will support the development of next-generation in-vehicle network solutions that address the mobility needs of tomorrow.”
