Microchip Expands Single Pair Ethernet Portfolio with New 10BASE‑T1S Devices Enabling Scalable Edge Connectivity

The devices are designed to meet AEC-Q100 and ISO 26262 standards; availability is currently limited to sampling.

Rhea-AI Summary

Microchip Technology (MCHP) introduced two 10BASE-T1S transceivers and an integrated endpoint family for automotive and industrial networks.

The LAN8679 uses an Open Alliance 3-Pin interface, while the LAN8680 adds power-management and system-control features. The LAN8660X/1X/2X family integrates a transceiver into a single-chip endpoint. All of the new devices are available in limited sampling. Microchip targets applications that connect devices at the edge of automotive, industrial and robotics networks.

News Explained

Microchip says its new 10BASE-T1S devices use multidrop networking, allowing multiple nodes to share a bus; the company says this reduces wiring weight and system costs and removes gateways.

"expansion of its 10BASE-T1S portfolio"

A networking standard that sends 10 megabits per second of data over a single twisted pair of wires, designed to connect many low‑speed sensors and devices on the same line rather than running a separate cable to each one. Think of it as a communal road for small data packets—cheaper, lower‑power, and easier to install than full Ethernet for every device—so investors watch it because it can lower deployment costs and expand markets for chips, industrial equipment, and connectivity services.

multidrop topology technical

"By leveraging 10BASE-T1S multidrop topology"

A multidrop topology is a wiring or network arrangement in which a single communication line or bus links multiple devices or nodes so they can send and receive data over the same physical medium; devices share the channel rather than having dedicated point-to-point links. It matters to investors because this design influences a product’s cost, scalability, performance and reliability—like several houses sharing one road, which can be cheaper but create bottlenecks or single points of failure.

transceivers technical

"10BASE-T1S PMD transceivers"

Transceivers are hardware devices that both send and receive electronic or light-based signals, acting like a two-way mailbox or translator that lets machines talk to each other. For investors they matter because transceivers are essential parts of networks, telecom gear and data centers; changes in demand, supply shortages, price shifts or new technology standards can directly affect manufacturers’ revenues, profit margins and the performance of connected systems.

New transceivers and integrated endpoint family simplify zonal architectures and reduce system complexity for automotive and industrial applications

CHANDLER, Ariz., Sept. 29, 2026 (GLOBE NEWSWIRE) -- Microchip Technology (Nasdaq: MCHP) today announces the expansion of its 10BASE-T1S portfolio with the introduction of the LAN8679 and LAN8680 10BASE‑T1S PMD transceivers, alongside the LAN8660X/1X/2X family of endpoints with integrated transceivers. Designed to support next-generation zonal architectures, these solutions deliver flexible, space-efficient connectivity that extends Ethernet to the network edge.

As automotive, industrial and robotics systems evolve toward fully Ethernet-based networks, designers face increasing demands for simplified architectures, reduced wiring complexity and efficient edge node integration. Microchip’s latest 10BASE‑T1S devices address these challenges and are designed to meet AEC-Q100 and ISO 26262 functional safety standards, building on Microchip’s VelocityDRIVE™ portfolio with additional multidrop connectivity solutions featuring a standardized, streamlined interface. 

The LAN8679 transceiver provides a standardized Open Alliance 3‑Pin (OA3P) interface in a compact 8‑pin VDFN package, supporting space-constrained edge nodes, while reducing pin count and design complexity. The LAN8680 builds on these capabilities by integrating System Basis Chip (SBC) features, including power management, system wake/sleep control and watchdog supervision. Both devices are engineered to enhance reliability and safety for demanding environments such as automotive and industrial applications.

“Microchip’s latest 10BASE‑T1S portfolio advances our commitment to enabling scalable, all‑Ethernet network architectures,” said Charlie Forni, corporate vice president of Microchip’s networking and connectivity business unit. “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.”

Complementing these devices, the LAN8660X/1X/2X endpoint family integrates a PMD transceiver into a single-chip Remote Control Protocol (RCP) solution. This approach enables designers to deploy compact, fully integrated edge nodes for applications such as control systems, lighting and audio without the need for external PHY components.

By leveraging 10BASE‑T1S multidrop topology, Microchip’s solutions allow multiple nodes—typically eight or more—to share a single bus line. This reduces wiring weight, lowers system costs and eliminates the need for gateways, making it easier to connect sensors and actuators directly to the network edge.

Microchip’s expanded Single Pair Ethernet portfolio targets a wide range of applications, including automotive zonal architecture, industrial automation, robotics and aerospace and defense systems. The products align with industry trends toward consolidated networks and simplified connectivity frameworks, enabling designers to implement efficient and scalable all-Ethernet architectures.
