m95p32 memory mapped

[AndreaCollamati]

Hi,

I would like to know if it's possible to use M95P32 in memory mapped mode on STM32G474 QSPI interface.

Thank you.

Hello @AndreaCollamati and welcome to the Community 🙂,

The STM32G474 has 2 types of SPI interface :

• Single SPI
• QuadSPI

The QuadSPI interface can be used to manage a single, double or quadruple SPI.

In that way, you will have the flexibility to communicate with the M95P32-I in single, dual or quad SPI.

Please take a look to this post Could you kindly share any reference schematics for SPI EEPROM M95P32-I interfacing with STM32 MCU?

Note that:

- Full duplex SPI transfer is not supported.

- Only read operations are allowed in memory mapped mode.

Thank you.
