Hello Frank,
 
Don't do it!!  Look at the "absolute maximum ratings" on the datasheet.
 
Depending on where the +5v is coming from, you can usually do something fairly simple.
 
Two diodes and a resistor can be used. Connect the two diodes in series to +5v.  The input is clipped to 3.6v - connect a resistor in series with the input.
 
 Another choice is an optical coupler.

Hi, I just need to know if its possible to feed in 5v as high input voltage to the GPIO module and McASP module configured as input or if a 3.3v regulator is needed for a c6713. The spec sheets only specify the minimum high input voltage of 2v and not the maximum..

Thanks,

Frank
