STM32N657X0H3 QSPI and SDRAM Integration

[Ajnas-C]

Dear Team,

We are currently working on a project based on the STM32N657X0H3Q MCU. As part of our design, we are planning to use a QSPI Flash and SDRAM instead of the OctoSPI Flash and HexaSPI PSRAM used in the reference designs.

Could you please share any reference schematics, application notes, or design examples that demonstrate the integration of QSPI Flash and SDRAM with the STM32N657X0H3Q?

Additionally, our design is highly space-constrained. If anyone has a reference for a minimal power supply/regulator design for the STM32N657X0H3Q, we would greatly appreciate it if you could share that as well.

We look forward to your response and guidance.

Thank you for your support.

Best Regards,
Ajnas C

Hello @Ajnas-C and welcome to the ST community,

AN4760 "Introduction to Quad-SPI interface for STM32 MCUs and MPUs"

To my knowledge there is no reference design STM32N6 + QSPI but you can inspire from other platforms like STM32H7 (STM32H743-EVAL schematic )

Same thing for SDRAM:

How to set up the FMC peripheral to interface with the SDRAM IS42S16800F-6BLI from ISSI

Good luck.
