SMSC’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 (0º to 85ºC) and industrial (-40º to 85ºC) 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**.
