I want to interface a 6502 to a modern microcontroller, a PIC32MZ. The PIC32 has some 5V tolerant pins, but not enough. Instead of using a level shifter, my idea is to run the PIC32 at 3.6V (which is allowed by spec) and wire it directly to the 6502. I've measured some voltages on the 6502's data and address lines and they seem to go no higher than 3.5 or 3.6V. Meanwhile, the "absolute maximums" spec for the PIC32 says that input pins can handle Vdd+0.3V.
It sounds like I can get away with this. Am I playing with fire, or am I OK?
Thanks,
Bob
