STM32H7 lowest possible standby current, any examples?

[Microman]

HI!

I am currently trying to minimise the standby consumption of a STM32H7 down to the

absolute minimum. Only the change of one Pin (PA0) is selected as wakeup event. No need for backup ram, Pin drivers, RTC nor anything else. The MCU shall only switch on and start booting from reset when the level of PA0 changes.

Are there any examples, guides how to reduce the power the absolute minimum?

I found AN4899 STM32 "GPIO configuration for hardware settings and low-power consumption" but that refers more to general power savings when running.

Hi @Microman​ ,

Look to the example available under STM32CubeH7 package. Ex: STM32Cube_FW_H7_V1.5.0\Projects\NUCLEO-H743ZI\Examples\PWR.

Hi Amel,

Thanks for the link, but I was not find anything about ROM to RAM boot, only RAM retainment and RAM low power modes in this examples.
