Is it not possible to connect a SDRAM to the STM32H755ZI microcontroller?

eeeeee · ‎2022-03-23

With other MCUs I get an additional SDRAM 1 and SDRAM 2 option. Or is it only not available to configure in CubeMX and I should code it myself?

Thanks in advance.

The LQFP144 package lacks necessary pins for SDRAM and thus is unavailable for selection in CubeMX.

Hello,

Unfortunately, SDRAM feature is not available on LQFP144 packages in STM32H7xx products.

The update of STM32H755 datasheet is ongoing and a fix will be available like done in the latest version of STM32H753 datasheet (DS12117 Rev 8) / Table 2.
