As the automotive industry transitions to zonal architectures for in-vehicle networking, designers face increasing challenges in connecting a growing number of sensors and actuators. Traditional approaches often rely on microcontrollers and custom software for each network node, resulting in greater system complexity, higher costs and longer development cycles. To overcome these obstacles, Microchip Technology introduced its LAN866x family of 10BASE-T1S endpoint devices with Remote Control Protocol (RCP), extending Ethernet connectivity to the very edge of in-vehicle networks and enabling the vision of Software Defined Vehicles (SDVs).
The LAN866x endpoints are designed to simplify network integration by serving as bridges that translate Ethernet packets directly to local digital interfaces. Unlike conventional solutions, these endpoints are designed to be software-less, reducing the need for node-specific software programming, streamlining silicon usage and physical footprint. With support for standard-based RCP protocols, the endpoints enable centralized control of edge nodes for data streaming and device management. By utilizing a 10BASE-T1S multidrop topology, this solution supports an all-Ethernet, zonal architecture that helps reduce cabling, software integration and cost.
By removing the need for software development at every node, the LAN866x endpoints are designed to reduce both hardware and engineering costs, accelerate deployment timelines and simplify system architecture. The endpoints are well-suited for critical automotive applications such as lighting—covering interior, front and rear headlamps, as well as audio systems and a wide range of control functions. In these applications, the endpoints provide direct bridging of Ethernet data to local digital interfaces controlling LED drivers for lighting, transmitting audio data to and from microphones and speakers, as well as controlling sensors and actuators over the network.
“With the addition of these RCP endpoint devices, Microchip’s Single Pair Ethernet product line empowers designers to realize a true all-Ethernet architecture for Software-Defined Vehicles,” said Charlie Forni, corporate vice president of Microchip’s networking and communications business unit. “We are committed to delivering innovative solutions and supporting our customers with global technical expertise, comprehensive documentation and development tools to further reduce design complexity and help them bring vehicles to market faster.”
