STM32F1 standby mode power consumption and noise

Question asked by VDM on Jun 20, 2013
Hi all,

On my STM32F102R8T6 board, when the STM32 goes into standby mode, power consumption goes down to a few µA.

But if I touch some pins of the STM32 with my finger or with a metal stick, power increases to several mA.
Then I remove it, and consumption decreases to a few µA.

It sounds like the STM32 power consumption is depending on EMI ..
The way to solve this issue would be to add pull-up or pull-down resistor on these pins, but I'd like to know if ever there's a software solution ...
It seems that internal pull-up and pull-downs are disabled while in standby mode ..

Anyone already faced this problem ?

Thanks for your help.
Best regards,
