Good morning to all,
I’d like to ask your advice.
I have to insert an external RAM for the framebuffer because the internal one is not enough for LCD that I will drive (LCD-TFT LVDS 7 inch 1024x600).
Which external RAM do you recommend? Could a QuadSPI work?
Solved! Go to Solution.

Hello,
You can use HSPI interface. You can refer to the STM32H7S78-DK board as reference (using APS256XXN-OBR memory):

I add that I have a micro LQFP176 pin.
Do I have to use the FMC? Quad or Octo SPI?

Thank you!
The problem is that in the package LQFP that I’m using it is not available the HexaSPI only Octa.

In that case use it in Octal mode:
