Power consumption does not fit with datasheet information

[Gaston]

Hi,

I'm running STM32C011F4U6TR using the LSI (32KHz) in a infinite loop.

Here's the current consumption I see from the STM32CubeMonitor-Power software

I expect to see around 80uA flat as datasheet shows at page 39

What could be the reason for the 170uA peaks I see using STM32CubeMonitor?

At these levels, current consumed by the rest of the hardware can easily be significant - even things like capacitor leakage.

Show the code, and details of the hardware:

Also the table specifies that the typical values are expected at 3.0V supply, when you are supplying 3.3V to your uC.

As @Andrew Neil said, any other enabled stuff can contribute. Have you disabled HSI ? Please show us the used source code.

Best regards.

Solved! I've disconnected the debug probe and run the code without SWD interface. Now it's working as expected

Thank you,

Yes, having a debug probe connected will certainly affect the current consumption!!
