I would like to know the maximum size of an external SRAM supported on STM32F407VGT6 via FMSC. Is it related to addresses?


According to the datasheet and the picture .. Is That mean that I can interface an external SRAM of 256 MB and a NAND Flash of 512 MB as a maximum size ?enter image description here

  • \$\begingroup\$ Did you read the manual? It says in the manual. And yes, it's related to addresses (as well as word-size). \$\endgroup\$ – DKNguyen Apr 26 at 20:24

  • \$\begingroup\$ On ST's website. They call it the "Reference Manual". You can't do anything with the processor without the manual. \$\endgroup\$ – DKNguyen Apr 26 at 23:03

  • \$\begingroup\$ If the maximum size is something that varies from part to part in the STM32F4 class of processors (I don't see why it would be unless some packages have fewer address pins available) then it may instead be in the datasheet. That's how ST divides everything up. Things specific to individual chips are in the datasheet (like package pinouts), and things that are common to a range of chips (like peripherals) are in the Reference Manual. \$\endgroup\$ – DKNguyen Apr 26 at 23:06
