    Interface Cortex M4 and PSRAM with different power supply voltage

    Dear all,

    could you please tell me if it is possible to interface a Cortex M4 (3.3V) with a PSRAM (1.8V) directly or do I have to add a logic level (Voltage Translation) between both?
    With kind regards,
    David

    Hi,

    I don´t know these devices, but I´m very sure the datasheets will tell you.
