AX88772ALF

AX88772CLF

AX88772ELF

The AX88772C USB 2.0 to 10/100M Fast Ethernet controller with Microsoft AOAC(Always On Always Connected) support is a high performance and highly integrated ASIC which enables a low cost, 

small form factor, and simple plug-and-play Fast Ethernet network connection capability for desktops, notebook PCs,

 Ultrabooks, cradles/port replicators/docking stations, game consoles, digital-home appliances, and any embedded system using a standard USB port.

Features
● Single chip USB 2.0 to 10/100M Fast Ethernet controller
