Overview

The LAN8720A-CP-ABC is a high-performance, low-power 10/100 Ethernet transceiver designed for small footprint applications. It utilizes Microchip flexPWR technology to reduce power consumption while providing a flexible RMII interface for connecting to modern microcontrollers and SoCs. This device includes an integrated 1.2V regulator and HP Auto-MDIX support, simplifying the bill of materials for embedded designs.

Why Choose This Part

This transceiver offers a significant reduction in power consumption, drawing only 26mA during 100BASE-TX traffic. The integrated 1.2V regulator and HP Auto-MDIX support reduce PCB complexity and external component count. Its compact 4x4mm 24-SQFN package is ideal for space-constrained embedded systems.
