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.

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 o...
