Voltage supported by EPM7032LC44-10

I would like to know whether EPM7032LC44-10 supports 5V as supply voltage? In datasheet it was mentioned that 3.3-V or 2.5-V power supply can be used. It is also mentioned that the device can be se...

    Your part number reference is for the original MAX 7000 series, which is 5.0V core and I/O only.
    It does NOT support 3.3V or lower I/O voltage levels.

    OTOH the MAX 7000B series has multivolt I/O capability, and can support 3.3V, 2.5V, or 1.8V I/O using the VCCIO pin connection.
    It does NOT directly support 5.0V I/O however, max VIN is something like 4.6V.

    Maybe you are asking about the MAX 7000A series. It has multivolt I/O that can support 5.0V, 3.3V, or 2.5V operation using VCCIO.
    So if you are asking about EPM7032ALC44-10 instead then the answer is yes it can support 5.0V I/O.
