STM32H743VGT6 and STM32H723VGT6 - XIP Support on QSPI?

[LP257]

We are currently using the STM32H723VGT6 MCU (1MB Flash) in our application.
We would like to clarify whether this MCU supports execute-in-place (XIP) from Quad-SPI flash or if Octal-SPI is required for XIP functionality.

In the future, if our application requires 2MB of internal flash, we plan to upgrade to the STM32H743VGT6, which is pin-to-pin compatible and also supports Quad-SPI.

As we are designing a common schematic for both MCUs, we would like to confirm:
Is a single Quad-SPI interface sufficient for enabling XIP on the STM32H723VGT6, or does it require an Octal-SPI interface for that purpose?

Hi @LP257 

This example should be helpful. Octal-SPI is not required for XIP functionality.

If the memory can be mapped it can be run. So yes this would work.

QUADSPI device are viable.
