The LAN8710AI-EZK is a compact, low-power Ethernet transceiver from Microchip (formerly SMSC), designed to support 10/100 Mbps Ethernet communication via MII (Media Independent Interface) or RMII (Reduced MII). It integrates HP Auto-MDIX (automatic cable crossover) and flexPWR power-saving technology, making it ideal for space-constrained embedded and IoT systems requiring reliable network connectivity.

Key Features

• Ethernet standards: Supports 10BASE-T and 100BASE-TX over twisted-pair cables via MII/RMII interfaces.
• Auto-MDIX: Automatically detects and configures straight/crossover cable connections, eliminating manual setup.
• flexPWR technology: Reduces power consumption to < 10 mW in low-power modes, ideal for battery-operated devices.
• Power supply: Operates from a 3.3 V supply with a 1.2 V core voltage, ensuring compatibility with modern microcontrollers.
• Compact QFN package: 5 mm × 5 mm × 0.9 mm (32-pin QFN) with 0.5 mm pitch, saving PCB space.
• Industrial-grade reliability: Functions across a -40°C to +85°C temperature range, suitable for harsh environments.
• RoHS-compliant and lead-free (Matte Tin plating).

Common uses include industrial IoT gateways, embedded networking devices, smart sensors, industrial automation systems, POS terminals, and low-power communication modules. Its small footprint and auto-configuration features make it a cost-effective choice for connecting edge devices to Ethernet networks.

Summary

The LAN8710AI-EZK combines high-speed Ethernet connectivity, compact design, and low-power operation to bridge microcontrollers and wired networks efficiently. Its auto-configuration capabilities and industrial-grade performance make it a versatile solution for embedded systems, IoT, and ruggedized applications requiring reliable Ethernet communication.
