AX88772C Product Introduction
1. Introduction
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.
The AX88772C can be used in any embedded system with a USB host microcontroller requiring
a twisted pair physical network connection. Featuring a USB interface (compliant with USB
specification V2.0 and V1.1) to communicate with a USB Host Controller, the AX88772C also
integrates on-chip Ethernet MAC and PHY (IEEE802.3 and IEEE802.3u compatible) and
embedded memory. Additionally, the AX88772C needs only a single 25MHz crystal to drive
both the USB and Ethernet PHYs.
The AX88772C offers a wide array of features including IPv4/IPv6 checksum offload engine,
Protocol Offload(ARP & NS), HP Auto-MDIX, and IEEE 802.3x and back-pressure flow
control. The AX88772C also offers multiple power management Wake-on-LAN features,
including Magic Packet, Microsoft Wakeup Frame, Link Status Change, 32 Microsoft Wakeup
Patterns and Wakeup Packet Indication that allows the AOAC platform to enter a low-power
“Connected Standby” state and wake on a desired network pattern.
The AX88772C 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.

6-2. Windows Production Test Tool
ASIX Electronics provides a Windows Production Test tool for users to run some basic network
function tests and program the EEPROM of their AX88772C based application systems during
production. This tool is used for testing the USB to Ethernet Network Adapter product that uses
ASIX AX88772C chip.
This tool supports to send/receive packets in different Ethernet speed modes, and program
EEPROM. This tool can be run on a Windows PC, which installs the special AX88772C
Windows test driver. This tool also needs a separate server PC to run the test server tool. The
test server tool on server PC can receive packets from the “device under test” product, and then
reply back.
