 AX88772A -- Single chip Low-pin-count USB 2.0 to 10/100M Fast Ethernet controller

Recent innovations in multimedia SoC's (System-on-chip) have been based on decreasing the physical form factor to reduce costs. The most efficient method of miniaturization is to decrease the pin count and utilize the serial interfaces such as SPI and USB, allowing the use of SPI flash and USB-LAN solutions, in favor of a parallel local/memory bus. Furthermore, USB's plug-and-play and 4-pin serial interface provides transfer speeds up to 480 Mbps, making it an ideal solution for miniature and portable handheld devices to quickly connect to networking peripherals. ASIX Electronics has released the AX88x72 series USB-to-LAN chips to satisfy the increasing market demands for adding networking capability for latest multimedia SoC's.

The AX88772A features a USB interface to communicate with a USB Host Controller and is compliant with USB specification V1.1 and V2.0. The AX88772A implements 10/100Mbps Ethernet LAN function based on IEEE802.3 and IEEE802.3u standards with 24KB of embedded SRAM for packet buffering. In addition, it integrates an on-chip 10/100Mbps Ethernet PHY, simplifying system design. The AX88x72A has a wide array of features including support for HP Auto-MDIX, Wake-on-LAN power management, and IEEE 802.3x/backpressure flow control. Optional serial interfaces such as I?C, SPI, and UART are provided as a control channel from the USB Host Controller to communicate with the external MCU chip.

The AX88772A, low-pin-count (64-pin LQFP) 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, UMPC's, cradles/port replicators/docking stations, game consoles, digital-home appliances, and any embedded system using a standard USB port.
