Hello, I am using stm32f407vgt6 that supports fsmc, I need to extend the RAM; is it possible to interface hyperbus RAM chips using the FSMC? if not what are the possible alternatives? kinly note stm32f407vgt does not support QSPI.

[JAbde.1]

Hyperbus RAMs requires 12 pins for implementation and offer decent speed. I have already 16 spare pins for the data/address and 10 other pins for fsmc handshaking.

have any one tested this option before? is this easily implemented using HAL library or a custom driver will do it?

I could not find documentation or use cases on the subject if you have please share.

Thanks in advance.
