    Q0001: Is AX78120 IC pin-to-pin compatible to MCS7820 IC?
    A0001: Yes, AX78120 IC is pin-to-pin compatible to MCS7820 IC.

    Q0002: Where can I obtain the latest AX78120 datasheet, reference schematic and other hardware design archives?
    A0002: Please register MyASIX membership (http://www.asix.com.tw/RegLogin.php?mod=thisis) and then download the latest AX78120 datasheet, reference schematic, PCB layout guide, etc. from AX78120 Product web page (http://www.asix.com.tw/products.php?op=pItemdetail&PItemID=258;74;109&PLine=74) directly.

    Q0003: Can ASIX help me to review my own AX78120 schematic and PCB layout?
    A0003: Yes, please deliver your own AX78120 schematic and PCB layout files to ASIX’s Support (support@asix.com.tw) for further review before making your own AX78120 PCB board.

    Q0004: Is the I2C EEPROM required for AX78120 2S applications?
    A0004: The I2C EEPROM is optional for AX78120 2S applications.

    Q0005: How to program AX78120 I2C EEPROM in-circuit?
    A0005: The AX78120 supports a Windows EEPROM Utility to program the I2C EEPROM in-circuit.

    Q0006: Does ASIX support RS-232/RS-485 transceivers solutions?
    A0006: Yes, ASIX also supports different RS-232/RS-485 transceivers solutions (i.e. Zywyn RS-232/RS-485 transceivers products). Please visit ASIX I/O Connectivity RS-232/RS-485 Transceivers Products Web page (http://www.asix.com.tw/products.php?op=ProductList&PLine=74&PSeries=122) for more details.

    Q0007: Can AX78120 install the original MCS7820 drivers directly?
    A0007: Yes, you should be able to install the original MCS7820 drivers on AX78120 applications directly. If you have any problems, please download the latest AX781x0 drivers from AX78120 Driver Download web page (http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=258) instead. The latest AX781x0 drivers supports all AX78140/AX78120/MCS7840/MCS7820/MCS7810 applications.

    Q0008: Where can I obtain the latest AX78120 drivers?
    A0008: Please visit AX78120 Driver Download web page (http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=258) to download proper drivers for your AX78120 target applications.

    Q0009: How to change the COM port number of AX78120?
    A0009: Yes, we can change the COM port number by using a drop down list located in AX78120 Windows COM Port Properties. To change the COM port number, go to "COM Port Properties => Features => COM Port Number".
