Microchip Expands Single Pair Ethernet Portfolio for Automotive and Industrial Edge Networks
Microchip Technology has expanded its 10BASE-T1S portfolio with new transceivers and integrated endpoint devices designed to simplify Ethernet connectivity at the network edge.
The new lineup includes the LAN8679 and LAN8680 transceivers, as well as the LAN8660X/1X/2X endpoint family. The products are aimed at automotive zonal architectures, industrial automation, robotics and other applications where designers are trying to reduce wiring, simplify network architecture and connect more edge devices directly to Ethernet.
The LAN8679 uses a standardized Open Alliance 3-Pin interface in a compact package, while the LAN8680 adds system-level functions including power management, wake and sleep control and watchdog supervision. Both are designed to support demanding automotive and industrial environments and are being developed with AEC-Q100 and ISO 26262 requirements in mind.
Microchip’s LAN8660X/1X/2X family goes a step further by integrating the transceiver into a single-chip Remote Control Protocol solution, reducing the need for separate PHY components in applications such as lighting, control systems and audio.
A key advantage of 10BASE-T1S is its multidrop architecture. Multiple nodes, typically eight or more, can share a single bus line, potentially reducing wiring weight, system cost and gateway requirements.
The launch strengthens Microchip’s position in the shift toward all-Ethernet architectures, particularly in vehicles and industrial systems where more sensors and actuators are being connected directly to distributed edge networks.
