STM32N6570-DK stop mode current consumption

[Val]

Hello ST,

 

I have used this project 

\STM32CubeN6\Projects\STM32N6570-DK\Examples\PWR\PWR_STANDBY_RTC

 

I have modified the project so that it enters stop mode instead of standby. The code that enters stop mode is put in a while(1) loop that looks like this

while(1)

  HAL_SuspendTick();

  HAL_PWR_EnterSTOPMode(0, PWR_STOPENTRY_WFI);

  SystemClock_Config();

  HAL_ResumeTick();

  Toggle_leds(); // toggles the green led 50 times 

}

 

All unused Gpios are set as analogue inputs 

Turned off RTC (wake up by button press instead)

put the NOR flash into deep power-down and tears down XSPI2/XSPIM, the IC3 clock divider and LSI. It keeps the flash chip-select held high with a pull-up.

 

 

Is the measured current higher than expected? How come VDIO is so high? VDDA1V8 can also be reduced i think, but how?

The board is powered via CN18.
