Supported PSRAM and Flash for the STM32N6xx

[RAdam.1]

Hey guys,

I'm looking for some suitable HexaSPI PSRAM and also the OctoSPI Flash for the STM32N645 board I am just building.. I cant find the parts used on the DK so do you have a list of supported memories? I need 256Mb PSRAM and will start with a 1Gb Flash as per the DK..

Hello @RAdam.1 

If you refer to the latest External Memory Manager Middleware,
STM32Cube_FW_N6_V1.3.0\Middlewares\ST\STM32_ExtMem_Manager\Release_Notes.html

You will find a list of NOR Flash SFDP from Winbond and Gigadevice manufacturer which are compatible with STM32N6.
Actually, concerning Hexa PSRAM/HyperRAM, only the APMemory APS256XXN-OBR-BG was validated on STM32N6.
After checking, it seems that the APS256XXN is available at Mouser.com.
