LAN8720A-CP
Every spec below is cited to the manufacturer datasheet. Pick your exact ordering code, compare the closest alternatives, then ask the assistant what it means for your design.
What the LAN8720A-CP family does
The LAN8720A/LAN8720Ai are small footprint RMII 10/100 Ethernet transceivers with HP Auto-MDIX support. These parts operate on a single 3.3V supply and feature a 24-pin QFN package measuring 4x4 mm. They support IEEE 802.3 Fast Ethernet with auto-negotiation and LVCMOS I/O voltages ranging from 1.6V to 3.6V. The integrated 1.2V regulator and flexible power management architecture enable use in set-top boxes, networked printers, routers, and digital media servers. Both commercial and industrial temperature grades are available to suit various embedded telecom and consumer electronics applications.
