The AX88772B Low-power USB 2.0 to 10/100M Fast Ethernet controller is a high
performance and highly integrated ASIC which enables low cost, small form factor, and simple
plug-and-play Fast Ethernet network connection capability for desktops, notebook PC’s, UltraMobile PC’s, docking stations, game consoles, digital-home appliances, and any embedded
system using a standard USB port.

The AX88772B features a USB interface to communicate with a USB Host Controller and is
compliant with USB specification V1.1 and V2.0. The AX88772B implements a 10/100Mbps
Ethernet LAN function based on IEEE802.3, and IEEE802.3u standards with embedded SRAM
for packet buffering. The AX88772B integrates an on-chip 10/100Mbps Ethernet PHY to
simplify system design.

The AX88772B provides an optional Multi-Function-Bus portion A and B (MFA and MFB)
for external PHY or external MAC for different application purposes. The MFA/MFB can be a
reduce-media-independent interface (RMII) for implementing 100BASE-FX Ethernet or
HomePNA functions. The MFA/MFB can also be a Reverse Reduced-MII (Reverse-RMII) for
glueless MAC-to-MAC connections to any MCU with Ethernet MAC RMII interface. In
addition, the MFA/MFB can be configured as general purpose I/O.
