While the automotive and industrial markets are widely adopting Single Pair Ethernet (SPE) solutions for network connectivity SPE, with its proven performance and reliability in automotive applications, is now also being deployed in other segments like avionics, robotics and automation.
Microchip’s LAN887x PHYs are designed to be fully compliant with IEEE 802.3bp for the 1000BASE-T1 specification and IEEE 802bw-2015 for the 100BASE-T1 specification.
Microchip has collaborated with the University of New Hampshire InterOperability Laboratory to create the development test platform for 1000BASE-T1 conformance. For many automotive and industrial applications that operate in harsh environments and need to withstand extreme temperatures, these devices are also designed to be ISO 26262 functional safety ready with ASIL B classification.
These devices provide advanced diagnostics including cable fault detection, signal quality indicator, link down and errors, built in self-test, and temperature and voltage monitoring for increased reliability. To provide flexibility with varying connectivity requirements across end applications, the LAN887x PHYs support Type A operation with cable lengths up to 15m and Type B operation to support extended cable lengths of up to 40m. Both operation types include four inline connectors.
The LAN887x is a low-power solution with EtherGREEN technology for increased energy efficiency. The OPEN Alliance TC10 Sleep and Wakeup feature provides additional power savings with a maximum of 16 µA standby power consumption, which extends operating time in battery applications. An optional integrated linear regulator can optimise BOM costs by reducing the number of components in the design.
The LAN887x PHYs are compatible with Microchip’s broad portfolio of microcontrollers (MCUs), microprocessors (MPUs), System-on-Chip (SoC) devices and Ethernet switches.
