STM32U0 Startup current

[JCard.3]

Hi @Amel NASRI,

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.

Thanks @Amel NASRI for curating the post.  Should I tag someone in particular for this question?

Cheers,

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.
