VCORE Supply for STM32H750IBT6

[MBair.1]

Hi all,

I am using STM's STM32H750IBT6 in our design.

I am in design stage and while designing for MCU power, I came across with following queries:

1. I understand that LQFP176 package does not have VDDLDO pin and for VCORE/VCAP I need to supply from external regulator. I assume that, as per Table 120 in datasheet, I can have . Is this understanding correct ?

2. Whether Voltage scaling is through hardware (through voltage divider) or software (through PWR_D3CR register). Whether it is on-the-fly ?

Please clarify.

Best Regards,

Hi all,

Just updated my question.

I am using STM's STM32H750IBT6 in our design.

I am in design stage and while designing for MCU power, I came across with following queries:

1. I understand that LQFP176 package does not have VDDLDO pin and for VCORE/VCAP I need to supply from external regulator. I assume that, as per Table 120 in datasheet, I can have 4 different supply value options from external regulator. Is this understanding correct ?

2. Whether Voltage scaling is through hardware (through voltage divider) or software (through PWR_D3CR register). Whether it is on-the-fly ?

3. Whether it has any power sequence requirements with VDD supply ? (could not get either in datasheet or in reference manual)
