STM32H7S7 PSRAM REFERENCE

[Hamady]

Hello ,

I'm desining a PCB for the H7S7 and the PSRAM on the discovery board is : APS256XXN-OBR-BG

But it seems to be NRND.

Can you confirm that this chip can be used in remplacement ?

APS256XXN-OBx9

Hello @Hamady ;

To check whether a device is supported by the XSPI interface, you need to refer to the device datasheet. Then, check the command format and order shared in the device datasheet must be aligned with the command format and order mentioned in the STM32 reference.

For more XSPI tips and tricks, I recommend you to look at Overall FAQs for QUADSPI/OCTOSPI/HSPI/XSPI - STMicroelectronics Community

Thank you.
