External memories and FMC

[GGran.2]

Hello,

in order to use external memories, is it mandatory to use the FMC?

Thank you

Hello @GGran.2 ,

That depends on the memory you need to interface.

There are other external memory interfaces such as QuadsPI, OCTOSPI, XSPI etc .. even I2C and SPI could be an interface for some memories...

You need to provide more details about the device you need to manage with STM32.

Thank you for the answer. My question was born following an answer to another my question in this forum concerning the speculation. In that answer a user wrote that the speculation on FMC is not useful while the speculation on external memories can be useful. Then I thought that the external memories can be acceded with different controllers and protocols.

FMC can be accessed the same way as internal memories taking into account some specificities: default MPU config, timings etc ..

Hope I answerd your question.

Hy GGran.2,

That depends on the memory you need to interface.
