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 set for 2.5-V, 3.3-V, or 5.0-V I/O pin operation.

    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.
