Hello everyone, may I ask what is the maximum clock frequency supported when the STM32H7's FMC peripheral controls SDRAM? Can it work stably if the frequency exceeds 200MHz, for example, 240MHz?

Thank you very much.?

Hello,

That depends on which STM32H7 you are talking about. You should always provide the MCU part number you are referring tor.

For STM32H74x , it's provided in the RM0433 / Table 55:
