Microchip Technology has introduced LAN867x family of 10BASE-T1S PHY Ethernet transceivers to expand Ethernet connectivity to the very edges of industrial networks, simplifying architectures and reducing risk for designers.
Microchip LAN867x Ethernet Physical Layer (PHY) transceivers are high-performance, small-footprint devices enabling connections to standard system devices including sensors and actuators that previously required their communication systems.
“Microchip’s 10Base-T1S technology provides an advantage for our endpoint-to-cloud integration, connecting products, controls, software and services more simply and cost-effectively,” said Julien Michel, Connected Systems project leader at Schneider Electric. “The technology will help to make the most of our energy and resources, bridging progress and sustainability for all.”
“For industrial system architects and designers, interconnection of many different communication devices and technologies often is difficult and error-prone,” said Matthias Kaestner, vice president, Automotive. “Using 10BASE-T1S Ethernet simplifies these interconnections, enhancing interoperability and speed, which is critical in the industrial environment.”
With the LAN867x devices, all-Ethernet infrastructures in OT and IT systems can be expanded to the edges of the network. Microchip’s LAN867x devices eliminate the need for gateways that in the past were needed to interconnect incompatible communication systems.
The single pair of wires reduces cost, while the multidrop bus architecture reduces the need for expensive switches and enhances scalability. Several nodes can operate on the same bus line with high data throughput.
Microchip’s LAN8670, LAN8671 and LAN8672 Ethernet PHYs are the industry’s first designed and validated to the new 10BASE-T1S standard for single-pair Ethernet released by IEEE.
10BASE-T1S addresses the challenges of creating all-Ethernet architectures for industrial applications such as process controls, building automation and consolidation of systems with multiple interconnection technologies.
The configuration enables a multidrop (bus line) topology, fewer cables, development on printed circuit boards, with up to at least eight nodes and up to at least a 25-meter range.
All-Ethernet infrastructures simplify architectures by using well-known communication and security mechanisms. This reduces cost and risk when designing new systems.
Additional advantages of Ethernet include the use of the same protocol independent from physical layer speed and operation within established security infrastructures and ecosystems.
