Hello STM32 Folks,
I am currently working on a design that requires interfacing a high-density RAM (256 Mb or 512 Mb) with a microcontroller (STM32U5) via the HyperBus interface. The RAM module is powered by 1.8V, while the STM32U5 needs to be powered by 3.3V to support other peripherals.
I have not been able to find an example implementation of this type of design and would appreciate any insights on how to implement this successfully, particularly regarding voltage level translation between the 3.3V MCU and the 1.8V RAM.
Thanks,
