Microchip Technology has introduced its LAN887x family of Ethernet PHY transceivers, (LAN8870, LAN8871, LAN8872) which are designed to support Single Pair Ethernet (SPE) solutions across various industries, including automotive, industrial, avionics, robotics, and automation. These transceivers offer data transmission speeds from 100 Mbps to 1000 Mbps and can support cable lengths of up to 40 meters, making them suitable for extended reach applications. The LAN887x PHYs are compliant with industry standards, specifically IEEE 802.3bp for 1000BASE-T1 and IEEE 802.3bw-2015 for 100BASE-T1, ensuring interoperability across different industries. The devices have been tested in collaboration with the University of New Hampshire InterOperability Laboratory (UNH-IOL) to ensure conformance with the 1000BASE-T1 specification. These transceivers are built for harsh environments and include ISO 26262 functional safety readiness with ASIL B classification, making them reliable for applications that require robustness and high reliability.
The LAN887x family also provides advanced diagnostics, including cable fault detection, signal quality indicators, and temperature and voltage monitoring. The devices support two types of operation: Type A, with cable lengths up to 15 meters, and Type B, which extends the cable length to 40 meters. Both types include four inline connectors. Additionally, the LAN887x PHYs are designed with EtherGREEN™ technology to minimize power consumption. They also include the OPEN Alliance TC10 Sleep and Wakeup function, which is useful for saving power in battery-operated applications. These PHYs are compatible with Microchip's range of microcontrollers, microprocessors, System-on-Chip (SoC) devices, and Ethernet switches, making them adaptable to various networking requirements.
