Part Number: UCD90240
Other Parts Discussed in Thread: UCD90120

Hello,

I'm Developing the off-Line Programmer for UCD90240, and the Burned file is HEX format Img file, How can I burn data to chip use PMBus? I have a document of "Configuration Programming of UCD Devices.pdf", but it just include UCD90120, and the version is 2012, does the UCD90240 commands is compatible with UCD90120?

Best regards,

Alan

    Hello

    Data flash hex file is a raw data file which can be written into the device with PMBUS_COMMAND. UCD90120 and UCD90240 uses the same command but the format is little different.

    In order to reduce the R&RD effort, Fusion GUI can generate the data flash write script which parse the data flash hex file and pack the data into the PMBUS_COMMAND format. External I2C master just need follow the format inside the script file to write into the device.

    Please refer below video how to export the data flash script file
    training.ti.com/fusion-power-designer-how-import-and-export-data-flash-script-files
    Once you get the script file, open it, your master i2c just follows the script.
