STM32 and external (S)DRAM

Can't be DRAM, must be SRAM. You can get 8M (4M x 16) e.g. CY62187EV30.

This seems an ambitious project for a microcontroller such as the STM32 which isn't really that suited to running code from external memory.

Thank you for the info about the SRAM module.

Why is the STM32 not suited to running code from external memory?

Do you see other options to run code from a SD-Card (or maybe an other Cortex-M3 microcontroller which is better suited for such thing)?

Because external bus access is relatively slow, and the part doesn't have a cache.
