Microchip Technology has introduced the LAN866x family of 10BASE-T1S endpoint devices, which incorporate Remote Control Protocol (RCP) to extend Ethernet connectivity to the outermost edge of in-vehicle networks. The devices are intended to support automotive manufacturers moving toward zonal architectures and software-defined vehicle platforms, where the number of distributed sensors and actuators continues to increase.
The LAN866x endpoints function as hardware bridges that convert Ethernet packets into local digital interfaces. This approach eliminates the need to integrate microcontrollers and node-specific software at each connection point, reducing design effort and simplifying the structure of distributed systems. By implementing RCP, the endpoints support centralised control and management while maintaining compatibility with standardised Ethernet protocols. Use of a 10BASE-T1S multidrop topology enables an all-Ethernet architecture designed to reduce cabling, improve scalability, and lower system costs.
According to Microchip, removing the requirement for software development at every node can shorten development cycles and reduce engineering and hardware expenses. The devices are intended for applications such as lighting systems, audio networks, and various distributed control functions. In these systems, the endpoints facilitate direct bridging of Ethernet data to LED drivers, microphones, speakers, sensors, and actuators.
The LAN866x devices are part of Microchip’s broader Single Pair Ethernet portfolio, which includes transceivers, bridges, switches, and associated development tools supporting 10BASE-T1S, 100BASE-T1, 1000BASE-T1, and higher-speed standards. These products are designed to streamline Ethernet deployment in automotive, industrial, and building-automation environments by reducing wiring needs and enabling interoperability across different network segments.
The LAN866x family is currently available in limited sampling. Additional information is available through Microchip sales representatives.
