Is STM32F44 supports 4Gb DDR4 SDRAM

[Predd.11]

I need to interface 4Gb DDR4 SDRAM with stm32f446vet6 controller

[waclawek.jan]

The 100-pin package does not have the FMC_SDCLK pin so it does not support SDRAM.

STM32 don't support DDR at all, only SDR.

Good joke.

Thanks for the information

is there any possibility to interface SDRAM DDR with STM32F44 without using FMC

[waclawek.jan]

There's no reasonable way I know of to interface DDR SDRAMs with STM32.

thanks sir,

Howmuch SDR SDRAM memory (maximum) can we interface by using FMC of STM32F446VE controller?

[waclawek.jan]

As I said above, the 100-pin package does not have the FMC_SDCLK pin so it does not support SDRAM.

For larger packages the limit is given by FMC itself; look at the FMC chapter in RM.
