UCD90120A: Clearing configuration

Part Number: UCD90120A

Is there an easy way to use the Fusion tool to clear the stored configuration of the UCD90120A.  Customer is developing a programming script and wants to try the script on a device already mounted on a board and already programmed. They would like to reset/clear the UCD configuration to its default state and then test the programming script. 

Maybe using the Data Flash Tool in the UCD3xxx & UCD9xxx Device GUI could work?

  • When connected to the device with the Fusion SW, open the configuration for the device to be erased then select Clear Configuration from the Tools dropdown.

  • Thanks, Brad. I didn't see this tool.
    As an alternate, is there a way to send a clear configuration command using a PMBUS script command?
  • Hi Mark

    Fuison GUi can export a data flash script file(File->export->data flash script), which contains all command to access data flash in the executive order. The script file can be followed by any I2C tool if custome do not want to use fusiton gui to download the user configuration.

    What's the purpose to develop your own program script? I would recommend to take a look of the data flash script file before any futher stpes.

  • Hi Yihe,
    I think the customer was using the Fusion Tool script export, but was looking at using the PMBUS Configuration Script method. They want a way to clear any previous configuration as part of this script. It sounds like they would instead need to run a Data Flash Script in order to include an initial flash erase.
  • Hi Mark

    The PMBus command script does not invlove the data flash operation directly. so the related commands are not included.

    I always recommend to use data flash file(either hex or script file) for programming to make sure hat all IOs are under controlled states.
