MCHPLAN8720AI
Overview
The LAN8720AI is a compact, high-performance 10/100 Ethernet physical layer transceiver (PHY) designed for industrial applications. It features an RMII interface to reduce pin count and utilizes flexPWR technology to minimize power consumption by integrating a 1.2V regulator.
Why Choose This Part
The LAN8720AI offers a significantly reduced BOM through its integrated 1.2V regulator and HP Auto-MDIX support, which eliminates the need for crossover cables. Its low power consumption and small 24-pin QFN package make it ideal for space-constrained, power-sensitive industrial designs.
Applications
Key Specifications
Getting Started
Evaluation can be performed using the LAN8720A Daughter Board (AC164138) which plugs into compatible Microchip development kits. Engineers should ensure the RMII clocking architecture is correctly configured, typically using a 50MHz oscillator or a clock provided by the MAC.
