STM32H743VIT6. FMC for SDRAM

Hi,

Is SDRAM over FMC supported in STM32H743VIT6 MCUs? I can't see this option in CubeMX, only NOR Flash/PSRAM/SRAM/ROM/LCD and NAND Flash. The datasheet says that SDRAM is not supported in LQFP144 packages, but my one is LQFP100.

Looking forward for any help.

Even fewer pins, so assuming more of the pins you'd need are absent...

Try the Data Sheet and then play Pin Bingo

SDRAM is not available on the LQFP100 either. FMC_A0, among many others, is absent on the pinout.

Thank you very much Tesla and TDK. I have checked the pinout once more and now I see that some necessary pins for SDRAM support are absent in LQFP100 package. It's a pity.
