Hello,

Unfortunately not. The max Flash size in F7 family is 2MB. But you can add external QSPI NOR Flash for memory extension.

Hi, Thanks for the reply. Is there any other MCU with more than 2MB flash in the same family?

The STM32F746G-DISCO has something like 16MB (128Mbit) of QSPI NOR memory externally for code, data and graphics. https://www.st.com/en/evaluation-tools/32f746gdiscovery.html
