Microchip Introduces New 10BASE-T1S Devices to Expand Single-Pair Ethernet Portfolio, Enabling Scalable Edge Connectivity
—New Transceivers and Integrated Endpoint Product Family Simplify Zonal Architectures and Reduce System Complexity for Automotive and Industrial Applications
Microchip Technology Inc. today announced the expansion of its 10BASE-T1S portfolio with the LAN8679 and LAN8680 10BASE-T1S PMD transceivers, along with the LAN8660X/1X/2X endpoint product family with integrated transceivers. Designed to support next-generation zonal architectures, these solutions provide flexible and space-saving connectivity, extending Ethernet connectivity to the network edge.
As automotive, industrial and robotics systems evolve toward all-Ethernet networks, designers face growing demands to simplify system architectures, reduce wiring complexity and efficiently integrate edge nodes. Microchip's new 10BASE-T1S devices are designed to address these challenges and meet AEC-Q100 automotive qualification and ISO 26262 functional safety standards. Building on Microchip's VelocityDRIVE™ family, these devices add multipoint connectivity solutions with a standardized reduced interface design.
The LAN8679 transceiver is offered in a compact 8-pin VDFN package and provides an Open Alliance 3-Pin (OA3P) standardized interface, supporting space-constrained edge nodes while reducing pin count and simplifying design complexity. The LAN8680 builds on this by integrating System Basis Chip (SBC) functions, including power management, system wake/sleep control and watchdog monitoring. Both devices are designed to enhance reliability and safety to meet the demands of harsh application environments such as automotive and industrial.
"Microchip's latest 10BASE-T1S portfolio further demonstrates 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 the simplicity of the OA3P interface with integrated endpoint functionality, these devices give designers greater flexibility to build efficient and reliable systems while significantly reducing complexity at the edge."
Complementing these devices, the LAN8660X/1X/2X endpoint product family integrates the PMD transceiver into a single-chip Remote Control Protocol (RCP) solution. This approach enables designers to deploy compact and highly integrated edge nodes for applications such as control systems, lighting and audio without the need for external PHY components.
By employing 10BASE-T1S multipoint topology, Microchip's solutions allow multiple nodes (typically eight or more) to share a single bus. This reduces wiring weight and system cost while eliminating the need for gateways, making it easier to connect sensors and actuators directly to the network edge.
Microchip's expanded single-pair Ethernet portfolio addresses a broad range of applications, including automotive zonal architectures, industrial automation, robotics, and aerospace and defense systems. These products align with industry trends toward network convergence and simplified connectivity frameworks, helping designers build efficient and scalable all-Ethernet architectures.
