Best Practices for Low Power Consumption in STM32 Projects

[sarivaaclinic]

I’ve been experimenting with STM32 microcontrollers for a battery-powered IoT project. While I’ve tried different sleep modes, I’m still struggling to balance performance and battery life.
Has anyone here implemented effective strategies for ultra-low power applications? Any tips or code examples would be appreciated.

Go through the reference manual and read about the various low-power modes. Choose the lowest power mode that still allows full functionality of your program. Then, go to the CubeMX examples to see an example program that puts the processor into that mode.

Hello @sarivaaclinic ,

Please have a look at these articles that will help you on getting started with low power modes:

• Low power - ST wiki page
• Introduction to Low power with STM32
• Tips for using STM32 low-power modes
• AN4777 How to optimize power consumption on STM32 MCUs

The two are, of course, fundamentally opposed!

Perhaps tell us what you've tried, and where you're stuck...

Not specific to STM32, but a general principle is to sleep as deeply as possible for as long as possible.

Does the STM32C0 family feature lower current in sleep mode and battery friendliness than U0 or other new family? Or is it mainly low cost and replacement of STM8?
