Choosing package for STM32H743 SPI HS

[cipek]

Hi,

I'm interfacing external ADC - 16 bit, 10MSPS (AD7626) with this microcontroller. STM32 SPI will work in slave mode, ADC will provide 80MHz clock. It will work in a burst mode - sampling 288 measurements x 16 bits at 5MHz.

I can't decide whether I need BGA for this or LQFP will be sufficient. I remember having issues with internal ADC under performing when used in LQFP package. I don't want to go with BGA unless I have to.

Cheers

Check DS, H7 can get 133 MHz at max, no way to 250-300.
