STM32U0 Startup current

JCard.3 · ‎2024-12-03

Thanks for sharing the info here. I'm really interested in low power MCUs. I do have one question: where can I find information about the startup current draw of this part? The datasheet has very good documentation on the supply current requirements in each low-power modes (6.3.5 Supply current characteristics). But on an energy-harvesting system, the startup current might also be limited. On my STM32L0 based designs, I noticed that the startup current was an order of magnitude higher than when running in low-power mode. Is this also the case on the new STM32U0? Is that documented anywhere?

Thanks!

Question originally asked a a follow-up of New possibilities for the ultra-low power segment!

Better to discuss it separately.

Hi @JCard.3 ,

As you can see, I edited my previous reply adding the internal tracking number of the request.

That should be handled after vacation period.
