Device Overview

Summary

Microchip's LAN8720A/LAN8720Ai are high-performance, small-footprint, low-power 10BASE-T/100BASE-TX transceivers specifically designed for today's consumer electronics, industrial and enterprise applications. The LAN8720A/LAN8720Ai are the industry's smallest footprint solutions with up to 40% lower power consumption than existing Microchip transceivers. The LAN8720A/LAN8720Ai have an integrated voltage regulator and ESD protection components to help reduce Bill of Material (BOM) costs.

The LAN8720A/LAN8720Ai connect via an RMII interface. These devices support HP Auto-MDIX†, employ Microchip's proprietary flexPWR technology and are available in both extended commercial (0° to 85°C) and industrial (-40° to 85°C) temperature range options.

Microchip's complimentary and confidential LANCheck® online design review service is available for customers who have selected our products for their application design-in*.

†HP Auto-MDIX eliminates the need for special "crossover" cables when connecting LAN devices together.

 

 

*The LANCheck online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
