FMC SDRAM design recommendations (STM32F446)

[Rihem_]

Hello,

I am designing a board with a STM32F446 connected to an IS42S16160H SDRAM through the FMC interface.

Could you please provide ST’s official recommendations regarding the use of series resistors on FMC lines?

• Typical values (22–33 Ω)?

• Any ST guideline or application note available?

Thanks,

Rihem
