As car manufacturers move towards zonal architectures, integrating a growing number of Sensors and actuators has become more complex. Traditional methods often require Microcontrollers and custom software for each node, adding cost and lengthening development cycles. Microchip’s new LAN866x endpoints AIm to address these challenges by eliminating the need for node-specific software.

The devices act as bridges, converting Ethernet packets directly into local digital interfaces. This software-less approach reduces silicon usage and physical footprint while simplifying system architecture. Supporting Remote Control Protocol (RCP), the endpoints enable centralised control of edge nodes for data streaming and device management. Using a 10BASE-T1S multidrop topology, the solution promotes an all-Ethernet zonal design, helping to cut cabling and integration costs.

According to Microchip, the LAN866x family is suited for critical Automotive functions such as lighting, audio systems, and various control applications. For example, the endpoints can link Ethernet data to LED drivers for headlamps, transmit audio between microphones and speakers, and manage sensors and actuators across the network.

Microchip’s Single Pair Ethernet portfolio includes transceivers, bridges, switches and development tools that enable high-speed data transmission over a single twisted pair cable. These solutions support standards from 10BASE-T1S to 1000BASE-T1 and are designed to simplify wiring, reduce costs and ensure interoperability for automotive, industrial and building automation applications.
