MAX10 FPGA high power consumption during programming of on-chip flash

During programming (with Quartus Programmer) of the on-chip flash (POF configuration into CFM memory) in MAX10 FPGA (10M16SAU324I7G, single 3.3V power supply), the current consumption on 3.3V jumps f...

Hello,


Possible device defect? How many you seeing this behavior?

The inrush current should not take more than a second.

    Hi Farabi,

    Thanks for the confirmation that this current is not correct. I do not see it as a typical "inrush" current becatuse it lasts for the entire duration of the flash programming.

    I have tested it on 2 devices, with the same effect.

    Could you confirm what is the expected current during programming of the internal flash in MAX10?

    Currently I suspect some layout issues, where some pins might not be connected as intended. My plan is to cleanup this layout, redo the PCB and test it again.

      Hello Peter,

      I am getting internal data for this request. I will get back to you once I have the information.
