Microchip Technology Inc., a leading provider of smart, connected, and secure embedded control and processing solutions, has announced the expansion of its Single-Pair Ethernet (SPE) portfolio with the LAN887x family of Ethernet PHY transceivers. These devices are designed to deliver exceptional interoperability and extended reach, offering support for network speeds ranging from 100 Mbps to 1000 Mbps using cable lengths of up to 40m.
SPE technology is increasingly adopted across industries such as automotive, industrial automation, avionics, and robotics due to its ability to reduce system cost, weight, and cable complexity. Microchip’s LAN887x PHY transceivers enhance connectivity solutions by meeting stringent industry standards, including compliance with IEEE® 802.3bp (1000BASE-T1) and IEEE 802bw-2015 (100BASE-T1) specifications. In collaboration with the University of New Hampshire InterOperability Laboratory (UNH-IOL), Microchip has also developed a test platform to ensure 1000BASE-T1 conformance, further solidifying its position as an industry leader in SPE innovation.
The LAN887x PHYs integrate a suite of advanced diagnostic tools, such as cable fault detection, signal quality indicators, link down/error notifications, and built-in self-tests, to enhance reliability and simplify maintenance. Designed to withstand harsh environments, these devices are ISO 26262 functional safety ready, achieving ASIL B classification, making them ideal for demanding automotive and industrial applications.
The devices support Type A operation for cable lengths up to 15m and Type B for extended reach of up to 40m, with both configurations featuring four inline connectors to meet diverse design requirements. Additionally, the EtherGREEN™ technology ensures low power consumption, while the OPEN Alliance TC10 Sleep and Wakeup feature minimizes standby power consumption to just 16 µA, making these devices suitable for energy-sensitive applications.
“Our comprehensive solutions, which include PHY transceivers, bridge devices, switches, and development boards, make it easier for designers to implement Single-Pair Ethernet technology into their designs,” said Charles Forni, Vice President of Microchip’s USB and Networking Business Unit., The low-power sleep, extended cable reach features, and functional safety support make our LAN887x devices versatile and robust solutions to support our customers’ expanding networking needs.”
Microchip’s LAN887x PHYs are designed to work seamlessly with the company’s broader portfolio of MCUs, MPUs, SoC devices, and Ethernet switches, offering customers a comprehensive ecosystem for implementing SPE technology. With solutions supporting data transmission speeds ranging from 10 Mbps to 1000 Mbps, Microchip continues to drive innovation in Ethernet technology across multiple industries.
To support developers, Microchip offers a wide array of tools, including Type A and Type B media converter kits, USB and PCIe® plug-in boards, SFP modules, and Linux® software drivers.
The Microchip LAN8870, LAN8871, and LAN8872 are available in production quantities. To learn more, contact a Microchip sales representative, an authorized distributor, or please click here.
