STM32F207 with external SRAM and NAND

Hello,

I have a question about STM32F207 :

Is it possible to connect an external SRAM + an external NAND flash on the same microcontroller through the FSMC controller ?

What is the effect in this case in term of performances ?

Thank you in advance for your response.

Thomas

Sure, they would each need their own chip select line and settings. The bus would adjust to the speed as it accesses the memory space associated with each device.

Suggest you look at the STM322xG-EVAL, both the software and schematics.
