    Q0001: Where can I obtain the latest AX88796C datasheet, reference schematic and other hardware design archives?
    A0001: Please register MyASIX membership (http://www.asix.com.tw/RegLogin.php?mod=thisis) and then download the latest AX88796C datasheet, reference schematic, gerber/PCB layout files and application design note from AX88796C Product web page (http://www.asix.com.tw/products.php?op=pItemdetail&PItemID=104;65;86&PLine=65) directly.

    Q0002: How to open the gerber files of AX88796C demo board?
    A0002: You can open the gerber files of AX88796C demo board by running ORACLE's AutoVue Evaluation Revision tool (30 days evaluation date). Please visit ORACLE's web site (http://www.oracle.com/) for more details.

    Q0003: How to open the PowerPCB PCB layout file of AX88796C demo board?
    A0003: You can open the PowerPCB PCB layout file of AX88796C demo board by running Mentor Graphics PADS Layout Product Evaluation Software (No time limitation but with limited function). Please visit Mentor Graphics' web site (http://www.mentor.com/) for more details.

    Q0004: Can ASIX help me to review my own AX88796C schematic and PCB layout?
    A0004: Yes, please deliver your own AX88796C schematic and PCB layout files to ASIX's Support (support@asix.com.tw) for further review before making your own AX88796C PCB board.

    Q0005: What kinds of host interfaces are supported by AX88796C?
    A0005: The AX88796C supports total seven different types of bus interfaces include 8/16 Bit SRAM-like bus interface, 8/16-Bit Address-Data Multiplex interface, Renesas CPU series bus interface, MCS-51 and SPI bus interface. The AX88796C can be configured to the specific bus type automatically by pull-up and pull-down the EECS/EECK/I_FULL pins.

     

    Q0006: What is the specification of 25MHz reference crystal of AX88796C demo board?
    A0006: The 25MHz crystal signals of AX88796C board should be winthin 25MHz +- 50ppm.

    Q0007: What is the reference Ethernet transformer of the AX88796C demo board?
    A0007: The reference Ethernet transformer on the AX88796C demo board is the Bothhand LU1S041X LF (Turns Ratio 1CT:1CT, Auto-MDIX) single RJ-45 connector module with integrated 10/100 BASE-TX magnetic.

    Q0008: What kind of EEPROM is supported by AX88796C?
    A0008: The AX88796C supports 16-bit mode 93C56 or 93C66 EEPROM.

    Q0009: Can the EEPROM be eliminated on AX88796C applications?
    A0009: Yes, the AX88796C EEPROM is optional if the MAC address can be stored on the Flash memory of your embedded system. The other EEPROM setting can also be configured by AX88796C registers directly.

    Q0010: Do I have to assign a unique MAC address to every AX88796C based devices?
    A0010: Yes, every Ethernet device must have a unique MAC address. Users should always assign a unique MAC address for every AX88796C based devices.

    Q0011: How do I register a MAC/Ethernet address from IEEE-SA?
    A0011: You must first have an OUI or an IAB, to which you then append 24 or 12 bits respectively, in a way that makes the resulting 48-bit number unique, i.e., your 24 or 12 bits must be unique within your organization, which will require coordination among all the users of your organization's OUI or IAB. Please visit the IEEE-SA web site (http://standards.ieee.org/regauth/registry_OUI.html) for details.

    Q0012: Are the AX88796C Ethernet LEDs behaviors programmable by software?
    A0012: Yes, AX88796C supports the LED Control Registors (LCR0, LCR1) to control the AX88796C Ethernet LEDs behaviors.

    Q0013: Do I need to modify AX88796C driver source code to work on my own target platforms?
    A0013: Yes, ASIX provides AX88796C Linux/WinCE/etc. drivers source codes and software programming guide for customer's reference so you can modify the AX88796C driver source code to work on your own target platforms directly.

    Q0014: Where can I obtain the latest AX88796C drivers source codes?
    A0014: Please visit the AX88796C Driver Download web page (http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=104) for details.

    Q0015: Where can I obtain the latest AX88796C Software Programming Guide?
    A0015: Please contact ASIX Sales (sales@asix.com.tw) directly.

    Q0016: Does AX88796C support the uIP TCP/IP stack porting source code?
    A0016: Yes, AX88796C supports a 8051 MCU uIP TCP/IP stack porting source code for customers' reference.

    Q0017: Is the AX88796C driver source code compatible with AX88796B driver source code?
    A0017: No, the AX88796C driver source code is different from AX88796B driver source code. Please refer to AX88796C driver source code to implement AX88796C driver on your target platforms directly.
