STM32H723ZET oscillator input limited to 48MHz - datasheet says 50MHz

[MHall]

In clock configuration for STM32H723ZET the oscillator input is limited to 4-48MHz.

The datasheet says 4-50MHz.

I'm using a 49.152MHz oscillator in bypass mode and this results in a clock tree error.

Hi @MHall​ ,

First let me welcome you to the STM32 Community :)

Thank you for this valuable feedback. I see your point and will bring it up internally to see how we can address the necessary modifications.

I will keep you posted with updates.

Thanks for your contribution.

Khouloud.

Hi @MHall​ ,

Good news :smiling_face_with_smiling_eyes: I am pleased to inform you that this issue is fixed in the latest STM32CubeMX version 6.3.0.

Now, CubeMX is showing the correct oscillator input limits matching values in the datasheet  :

 

Thanks for your contribution.

Are you running at nominal voltage with sufficient decoupling capacitors?

[MHall]

@Uwe Bonnes​ Yes that is my plan. At the moment I'm searching for the right STM32H7 controller / package.

Normally, DS is the authoritative information source, so you can ignore any constraints of CubeMX or any "library".
