AX88772B -- Low-Power USB 2.0 to 10/100M Fast Ethernet Controller |
|
| The AX88772B Low-power USB 2.0 to 10/100M Fast Ethernet controller 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 PC's, Ultra-Mobile 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 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 HomePlug, HomePNA, etc. 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.
