Microchip introduces the first auto-scale 10BASE-T1S Ethernet devices

     Automotive designers want to replace traditional gateway subsystems with technologies that can migrate applications to Ethernet networks to easily access information from the edge to the cloud. In an effort to deliver vehicle-scale Ethernet solutions to Oems, Microchip Technology announced the first vehicle-scale Ethernet PHYs. The 10BASE-T1S family of devices is AEC-Q100 Level 1 qualified and includes models LAN8670, LAN8671 and LAN8672.

     The LAN867/1/2 10BASE-T1S Ethernet PHY is functionally safe and is designed for ISO 26262 applications. With these devices, low-speed devices that previously required their own communication systems can now be connected to standard Ethernet systems for automotive applications.

     Matthias Kaestner, vice president of Microchip's Automotive Products business unit, said: "Microchip continues to prioritize connectivity solutions for the automotive industry with the introduction of the 10BASE-T1S family. This new technology will connect sensors and actuators used in the physical world all the way to the cloud, making a seamless Ethernet architecture ubiquitous."

     Connecting multiple Ethernet PHYs to a common bus line makes it simpler to deploy automotive applications on a single popular architecture, while saving deployment costs by reducing cabling and switch ports. The LAN8670/1/2 enables the network edge to easily communicate with the rest of the network infrastructure using Ethernet and Internet Protocol (IP). These devices include advanced PHY diagnostics to provide users with troubleshooting capabilities. In addition, the sleep/wake function supports a low power mode.

     Features of the 10BASE-T1S device include 10 Mbps, half-duplex mode, flexible point-to-point topology, multiple bus lines and use of a single pair of balanced wires. These devices also feature enhanced electromagnetic compatibility/electromagnetic interference (EMC/EMI) performance and support for time-sensitive networking (TSN), which enables synchronous timing of long-distance Ethernet networks. Time synchronization is critical for many applications throughout the automotive partitioning architecture.

     Microchip was one of the major contributors to the development of the IEEE automotive 10BASE-T1S technical standard. This technology simplifies system design by extending Ethernet coverage to devices that are typically at the very edge of the network.
