LAN8710A/8720A Small-Footprint, Low-Power Consumption, Full-Featured 10/100 Ethernet Transceivers 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(R) technology and are available in both extended commercial (0 to 85C) and industrial (-40 to 85C) temperature range options. SMSC's complimentary and confidential LANCheck(R) online design review service is available for customers who have selected our products for their application design-in**.
