I set several unused pins in stm32u5 to floating as hardware and set them to low output by pushpull for ESD protection.The microcontroller was heating up abnormally when I looked at it with a thermo camera, and I found that the current consumption of...

I want to write firmware to stm32u575 using cube programmer, but when I do download from the erase & programming section, it fails to write.Of course, I have turned off the "skip flash erase before programming" checkbox.However, if I run the program ...

sorry, I haven't found a fundamental solution.

Sorry for the delay in replying.We have found the cause of the problem and are successfully moving toward mass production.The cause was a bug in our software, which supplied the clock to the MCU's built-in opamp mounted on a pin that was set to Low a...

sorry.this problem source is by my circuit design cause there was no problem encounted in stm32 nucleo u575zi-q.I will look into the cause now.

The part used is STM32U575QGI6.As for the PCB and firmware, they are our assets and I cannot give them to you at my discretion. I am sorry. I can give you a fragment of information.I will talk to my boss and try to do the same experiment with ST eval...

Yes, I understand that.However, I had dropped unused pins to Low in reference to AN4899 to increase ESD immunity.This caused this phenomenon, so I set the input to analog floating and the abnormal current consumption disappeared, so I found that the ...
