Microchip Technology extends Ethernet to the edge for automotive and
Microchip Technology has expanded its Single Pair Ethernet portfolio with three new device families designed to push Ethernet connectivity deeper into vehicles, factory floors and robotic systems. The LAN8679 and LAN8680 transceivers, together with the integrated LAN8660X/1X/2X endpoint family, target what the industry calls "zonal architectures," where centralised compute nodes replace the tangle of point-to-point wiring that currently runs through modern cars and industrial machines.
The move is incremental in isolation, but it sits inside a structural shift that is reordering capital and engineering priorities across at least three sectors simultaneously. Automotive OEMs, industrial automation vendors and aerospace primes are all converging on all-Ethernet backbones, and the component race to enable that transition is accelerating.
Simplifying the node
The LAN8679 offers a compact Open Alliance 3-Pin interface in an 8-pin package, cutting pin count and PCB area for space-constrained edge nodes. The LAN8680 goes further by folding in System Basis Chip features: power management, wake/sleep control and watchdog supervision in a single package. Both devices meet the AEC-Q100 automotive-grade qualification and ISO 26262 functional-safety standard, the twin gatekeepers for any component that wants to sit inside a production vehicle.
The LAN8660X/1X/2X family takes a different approach, integrating the physical-medium-dependent transceiver directly into a Remote Control Protocol endpoint. The result is a single-chip solution for edge nodes running control systems, lighting or audio, removing the external PHY component that traditionally added cost and board space.
Charlie Forni, corporate vice president of Microchip's networking and connectivity business unit, said: "By combining OA3P interface simplicity with integrated endpoint functionality, these devices give designers the flexibility to build efficient, reliable systems while significantly reducing complexity at the edge."
A core technical benefit is the 10BASE-T1S multidrop topology, which allows eight or more nodes to share a single bus line. Fewer cables means lower wiring weight, which matters considerably in electric vehicles where every gram affects range, and in drones or aerospace platforms where payload margins are tight.
The convergence read-across
The deeper strategic story is about network architecture convergence across sectors that have historically run entirely separate wiring standards. Automotive Ethernet was once a niche premium feature; it is now a prerequisite for the zonal architectures that underpin autonomous-driving compute stacks, over-the-air software update pipelines and in-vehicle data collection for AI training. Industrial automation is undergoing the same transition, with legacy fieldbuses such as CAN and PROFIBUS giving way to Ethernet-based fabrics that can carry both operational-technology commands and IT-side telemetry on the same wire. Robotics follows closely: next-generation robotic cells require deterministic, high-bandwidth links between sensors, actuators and edge-compute modules, and single-pair Ethernet is a leading candidate to supply them.
For capital allocators, this convergence creates an interesting cross-sector signal. Investment in automotive Ethernet silicon is no longer separable from investment in industrial IoT or robotics infrastructure. The companies that own the physical-layer components at the network edge hold a toll-road position: every sensor, actuator and controller that joins an all-Ethernet architecture needs a transceiver or endpoint chip. Microchip's portfolio expansion is a direct bid to occupy that position across four end markets simultaneously: automotive, industrial, robotics, and aerospace and defence.
The broader competitive landscape includes NXP Semiconductors, Texas Instruments and Analog Devices, all of which have active Single Pair Ethernet programmes. The race is less about raw technical differentiation at this stage and more about design-win momentum: whichever supplier gets its reference designs into the next generation of automotive platforms or collaborative-robot controllers tends to retain that socket for a production lifecycle measured in years, not quarters.
Microchip's new devices are currently available in limited sampling. Volume production timelines have not been disclosed, which means the more consequential signal will come when major Tier-1 automotive suppliers or industrial automation vendors confirm design wins built around the new portfolio.
