KSZ8041NLI-TR 10/100 Ethernet PHY
The KSZ8041NLI-TR is a single-port 10/100 Ethernet PHY from Microchip Technology, designed for industrial automation, embedded systems, and IoT connectivity. This IEEE 802.3-compliant transceiver supports MII/RMII interfaces for seamless integration with MCUs, FPGAs, and switches, delivering low-latency communication for real-time control networks. The device operates from a 3.3V supply with 1.8V/2.5V/3.3V-tolerant I/Os, ensuring compatibility with modern low-voltage processors. Its advanced cable diagnostics detect open/short faults and cable length, simplifying network troubleshooting in factory automation and smart infrastructure.
The KSZ8041NLI-TR features energy-efficient Ethernet (EEE) support, reducing power consumption by up to 50% during idle periods, ideal for battery-powered IoT gateways. Packaged in a compact 32-pin QFN (5mm×5mm), it includes ±8kV ESD protection and operates over the industrial temperature range (-40°C to +85°C), ensuring reliability in harsh electrical environments. Microchip provides Linux drivers and hardware design guides, accelerating deployment in motor control systems, HVAC controllers, and energy meters.
