Microchip’s lan867x series Ethernet PHY is the first to implement IEEE ® 10base-t1s is a product of single pair Ethernet technical standard, which is used to connect industrial network equipment.

As digital networks increasingly connect machines, production line equipment and robots, intelligent manufacturing is improving automation efficiency. Operating technology (OT) and information technology (it) networks, which are critical to the industrial Internet of things (iiot), rely on Ethernet to achieve interoperability, speed up data transmission and ensure security. Microchip Technology Inc. (American microchip technology company) today launched a new solution lan867x series 10base-t1s PHY, which extends Ethernet connection to the edge of industrial network, simplifying architecture and reducing risk for designers.

Microchip’s new lan867x Ethernet physical layer (PHY) transceiver is a high-performance, small-size device that can connect with standard system equipment (including sensors and actuators), which previously needed their own communication system.

With lan867x devices, the all Ethernet infrastructure in OT and it systems can be extended to the edge of the network. Microchip lan867x devices eliminate the need for gateways, which used to interconnect incompatible communication systems through gateways. A single pair of wires reduces costs, while a multi fork bus architecture reduces the need for expensive switches and enhances scalability. Multiple nodes can run on the same bus line with high data throughput.

Microchip’s lan8670, lan8671 and lan8672 Ethernet PHY are the first products in the industry designed and verified according to the latest 10base-t1s single pair Ethernet standard released by IEEE. 10base-t1s solves the challenge of creating an all Ethernet architecture for industrial applications, such as process control, building automation and system integration using multiple interconnection technologies. This configuration realizes multi bifurcation (bus line) topology, reduces cables, can be developed on printed circuit board, has at least 8 nodes, and the support range is no less than 25m.

All Ethernet infrastructure simplifies the architecture and reduces the cost and risk of designing new systems by using common communication and security mechanisms. Other advantages of Ethernet include using the same protocol independent of physical layer speed and operating within the established security infrastructure and ecosystem.

Julien Michel, head of Schneider electric interconnection system project, said: “microchip’s 10base-t1s technology provides advantages for our end-to-cloud integration, connecting products, control systems, software and services in a simpler and more economical way. This technology will help make full use of our energy and resources and promote the progress and sustainable development of relevant parties.”

Matthias kaestner, vice president of microchip automotive products, said: “for industrial system architects and designers, the interconnection of many different communication devices and technologies is often very difficult and error prone. The use of 10base-t1s Ethernet simplifies these interconnections and improves interoperability and speed, which is very important for the industrial environment.”

Lan867x expands microchip’s product portfolio and overall system solutions for industrial applications, including single chip microcomputer (MCU), microprocessor (MPU) and switch with Ethernet interface, as well as development tools, evaluation board and support.
