Hi everyone,
Has anyone interfaced the MX66UW1G45GXDI00 (1Gbit octal SPI Flash) with the STM32N6 XSPI controller?

Any working example or experience would help.

Thanks!

Hello @GBA;

 

The MX66UW1G45GXDI00 is compatible with STM32N6 XSPI. This memory is integrated into STM32N6570-DK board.

Two examples  with MX66UW1G45GXDI00 and STM32N6570-DK board are available in STM32CubeN6 firmware package: XSPI_NOR_AutoPolling_DTR  and XSPI_NOR_MemoryMapped_DTR you can refer to these examples.

For the memory datasheet, Macronix not providing the MX66UW1G45GXDI00 datasheet, they’d claimed it was controlled. I will recommend you to check with memory provider.

 

I hope this answer your request.

Thank you.
