STM32H753ZIT6 VCAP pins

Hi,

Vous avez dit :

I’m using the STM32H753ZIT6 in my design and I’m looking for clarification on the correct way to connect the VCAP pins. Since the LQFP144 package does not support the VDDLDO pin, what is the recommended capacitor configuration for VCAP?
Should I use 2 × 100 nF capacitors to GND, or 2 × 2.2 µF to GND?

Additionally, if there is no VDDLDO pin available on this package, how does the VCORE receive its internal supply voltage? Is there an internal voltage regulator that is powered directly from VDD?

Thanks in advance for the guidance!

    Hi,

    as you see in ds :

    Vcap is 2 x 2u2  , = core supply caps. NEEDED .

    Not difficult, clear now ?
