STM32H7 Pseudo SRAM compatibility

Ajaho · ‎2024-05-04

Hi,

I'm looking for SRAM memory for STM32H757xI and found this

https://eu.mouser.com/ProductDetail/ISSI/IS66WVS4M8BLL-104NLI?qs=doiCPypUmgHfByEUFkOsAw%3D%3D

Does such kind or SRAM memory work with this MCU model?

Thanks.

Hello,

I don't see an issue with using that PSRAM on FMC interface. You can refer to the STM32H743-Eval board schemtics downloadable from here to inspire from on how to connect that device. It uses IS61WV102416 device.

Also inspire from its driver from here.

Hope it helps.

Attaching such kind of memory is the task of FMC and STM32H757 has FMC. So it is possible, but requires you to setup up FMC for that device.

...and always match those trace lengths! ;)
