LAN8720A

In Production

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°C to 85°C) and industrial (-40°C to 85°C) temperature range options.†HP Auto-MDIX e...

    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°C to 85°C) and industrial (-40°C to 85°C) temperature range options.


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