SMSC LAN8720A Ethernet Transceiver

LAN8720A Ethernet TransceiverSMSC's LAN8710A and LAN8720A are high-performance, small-footprint, low-power 10BASE-T/100BASE-TX transceivers specifically designed for today's consumer electronics, industrial and enterprise applications. The LAN8710A/8720A are the industry's smallest footprint solutions with up to 40% lower power consumption than existing SMSC transceivers. The LAN8710A/8720A have an integrated voltage regulator and ESD protection components to help reduce Bill of Material (BOM) costs.

The LAN8710A connects to the MAC layer using a variable voltage, digital standard MII or RMII interface, while the LAN8720A connects via an RMII interface. Both devices support HP Auto-MDIX†, employ SMSC's proprietary flexPWR technology and are available in both extended commercial (0° to 85°C) and industrial (-40° to 85°C) temperature range options.

SMSC'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 SMSC's Program Terms and Conditions and requires an SMSC E-services account.
