Vbat minimum on STM32N6

[bashReflex]

I am designing the power system for an application using the STM32N645. In the datasheet for the STM32N6x5 minimum Vbat is defined as "TBD". In the STM32N6570-DK schematic the Vbat rail is set to 3.3V. If it can operate at 1.8V it would simplify the power architecture.

 Does anyone have any experience with running it at 1.8V? Or is there a timeline for when this specification will be released?

Thanks!

Hello @bashReflex and welcome to the Community;

I will check the minimum VBAT value on STM32N6 internally. I will get back to you as soon as possible.

Internal ticket number: 215811 (This is an internal tracking number and is not accessible or usable by customers).

Thank you.
