I am looking for a STM32 MCU with, - Either Two 10-bit ADC with 8 channels each with a sampling rate of 8 MSPS - Or One 12-bit ADC with 8 channels with a sampling rate of 8 MSPS Is there an option to match my requirement? Thanks in Advance.

Those are beyond the capabilities of the STM32H7 which is the fastest.

Thanks for your response @TDK​ . Much appreciated.

ST Team, any alternate recommendations to meet this requirement with a mix and match of ST components?

If I'm not mistaken, 8 x 8 = 64 MSPS, or mega samples per seconds? Considering constrains of ADC, DMA & uCPU:

H7 limited by ADC - 10.6 MSPS triple interleaved, necessary ~6 pieces;

G4 -//- 20 MSPS 5xADC, 3 pieces.

the best option probably stm32G474. No way to sample continuously, due memory limits

@MasterT​  STM32G474 is a good suggestion. Thanks. I am looking it up in detail.
