Overview

The LAN8720A-CP-TR is a high-performance, small-form-factor 10/100 Ethernet physical layer transceiver (PHY) with an RMII interface. It utilizes Microchip flexPWR technology to achieve low power consumption while supporting standard features like HP Auto-MDIX and an integrated 1.2V regulator.

Why Choose This Part

It offers a reduced pin count interface (RMII) which simplifies PCB routing and saves MCU pins compared to standard MII. The integrated 1.2V regulator allows for single-supply operation from 1.6V to 3.6V, reducing external component count and board space in dense designs.

Applications

Industrial Networking
Used in networked sensors, controllers, and instrumentation requiring 10/100 Mbps connectivity over RMII.
Set-Top Boxes
Provides the physical layer connection for consumer entertainment devices and media players.
Networked Printers
Facilitates high-speed data transfer for office equipment and print servers.
