Microchip Technology Inc. and Hyundai Motor Group launched a collaboration to evaluate 10BASE-T1S Single Pair Ethernet (SPE) as a foundation for next-generation in-vehicle networking. The effort focuses on simplifying vehicle architectures as automakers shift toward software-defined vehicles and higher levels of connectivity.
The companies are assessing how 10BASE-T1S can replace a mix of legacy and proprietary in-vehicle buses with a unified Ethernet fabric. Single Pair Ethernet enables multi-drop communication over a single twisted pair, reducing wiring complexity while supporting deterministic, low-latency connectivity across sensors, actuators, and electronic control units.
As part of the collaboration, Hyundai Motor Group is integrating Microchip’s 10BASE-T1S solutions into future vehicle platforms, with an emphasis on electric vehicles, autonomous driving, and smart mobility systems. Microchip is providing early product access and technical support to accelerate platform validation and shorten development cycles.
