On H7 MCU, waht is the minimum freq of SCK on SPI block? I try to connect a ADC with max SCK 3.2Mhz to H7's SPI port.

For master, it'll depend on your clock settings. you can max out the prescaler and set the input clock as low as possible.

You shouldn't have a problem getting it below 3.2MHz regardless of clock settings.
