|Q0016: ||What kind of EEPROM is supported by AX88178A?|
|A0016: ||The AX88178A supports 3.3V to 5V 16-bit mode 93C56/93C66 serial EEPROM. Please refer to AX88178A USB 2.0 to Gigabit Ethernet Application Design Note for details.|
|Q0017: ||Can I eliminate the EEPROM on AX88178A applications?|
|A0017: ||The AX88178A supports a 64-byte eFuse that is a one-time programming ROM for an alternate solution to store the required hardware configuration data in production. We strongly suggest customers to reserve the EEPROM location on AX88178A PCB board for flexible designs even if you plan to use the AX88178A eFuse for hardware configuration. Please refer to AX88178A EEPROM User Guide for details.|
|Q0018: ||How do I program the AX88178A EEPROM or eFuse?|
|A0018: ||AX88178A supports some default settings inside chip hardware to enable it to communicate with USB host controller during enumeration when the AX88178A EEPROM is blank (prior to being programmed). The default settings inside chip facilitate users to update the EEPROM contents through a Windows PC during R&D validation process or program a blank EEPROM or eFuse during manufacturing process.|
ASIX Electronics provides Windows/Linux SROM programming tools for users to easily program AX88178A EEPROM or eFuse on a typical Windows/Linux platforms. These AX88178A SROM programming tools support to customize the MAC address, Serial Number, Vendor ID and Product ID, etc. for AX88178A based application systems in mass production.
Alternatively, users can pre-program the blank EEPROM on a 3rd Party Universal Programmer before soldering the EEPROM onto the AX88178A application device. You MUST assign a unique MAC address in the EEPROM for every AX88178A device.
Please refer to AX88178A EEPROM User Guide for more detailed EEPROM/eFuse design notes.
|Q0019: ||Do we need to register our own VID/PID for our AX88178A based application systems or can we use the ASIX's VID/PID?|
|A0019: ||The answers to above questions really depend on user's product applications and target market, which can be different on individual cases. Below gives customers some general guidelines about whether one can use ASIX's VID/PID or one should better register its own one with USB-IF.|
1.Case where it is OK to use ASIX Electronics's VID (0B95h) and PID (178Ah):
You may be able to use ASIX Electronics' VID and PID when your AX88178A based application system can simply work with AX88178A standard drivers provided by ASIX without any modification and you don't have any concern from business and product marketing perspective to use the same VID and PID on your products as ASIX's other customers who are also using ASIX's VID and PID. ASIX Electronics would like to request customers to inform ASIX sales staffs by sending us email at email@example.com beforehand if you would like to use ASIX Electronics VID and PID for your products.
In other words, if your AX88178A based application system requires you to modify AX88178A driver on your own or by ASIX support team, you might have to register your own VID and PID. This can avoid your end customers from going to ASIX web site to download the AX88178A standard drivers which may not be suitable to work with the specific AX88178A based application system.
2.Cases requiring you to use your own VID and PID
(1) Your AX88178A based application systems can't work directly with AX88178A standard drivers which ASIX Electronics release on its web site and your target application system (such as USB dongle or docking station) may allow your end customers to update the standalone AX88178A driver by themselves after sales. In that case, you MUST assign your own unique VID and PID for your AX88178A based devices.
(2) For brand name products, you probably don't want your AX88178A based devices to become compatible with other company's AX88178A based devices. In this case, you should consider assigning your own unique VID and PID for your AX88178A based devices.
You can register your own VID from USB Implementers Forum, Inc. and define the PID based on your company rules.
|Q0020: ||How do I register a Vendor ID from USB-IF?|
|A0020: ||If you are a new USB product developer looking to get a Vendor ID for your company, you can register a Vendor ID from USB Implementers Forum, Inc. Please visit the USB-IF web site (http://www.usb.org/developers/vendor/) for details.|
|Q0021: ||Do I have to assign a unique MAC address to every AX88178A based devices?|
|A0021: ||Yes, every Ethernet device must have a unique MAC address. Users should always assign a unique MAC address in the AX88178A EEPROM for every AX88178A based devices.|
|Q0022: ||How do I register a MAC/Ethernet address from IEEE-SA?|
|A0022: ||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.|
|Q0023: ||Do I have to assign a unique serial number to every AX88178A based device?|
|A0023: ||No, it depends on the real requirement of your AX88178A target application. If users need to install more than one AX88178A based devices on your target application, you should assign a different serial number in the EEPROM for every AX88178A device.|
If your target application always uses one AX88178A device, you can consider assigning the same serial number in the EEPROM for every AX88178A device for easy maintenance in mass production, especially if you plan to use a Windows PC to test AX88178A based devices repeatedly during mass production test.
|Q0024: ||Did the AX88178A pass the USB-IF compliant certification?|
|A0024: ||Yes, AX88178A demo board was certified by USB-IF.|
