STM32H725REV Max Core Clock

[TKana.1]

Hi,

 

Planning to use VFQFPN68 package. I am confused about the max core clock I can use. CubeMx shows 550MHz for every "Power Regulator Voltage Scale (0-3)".

I remember reading VFQFPN68 has only DCDC solution so max core clock is 400MHz

 

Can anyone explain please?

Thanks,

Tim

Max clock speed is 550 MHz.

Achieved only in VOS0 and BOOST.

Hello,

I think you are talking about STM32H7 dual core that has that restriction in SMPS mode:

But STM32H723 doesn't have such restriction in SMPS mode:
