Yes I'm aware of the ESD issues, I have series resistors in line to the device. I sometimes add a DALC208SC6 device to absorb any stray static. The tiny logic is a good suggestion, but I have the board layout complete, so next time.

I prefer the TinyLogic parts rather than just ESD diodes, as they protect against an invalid voltage on the JTAG pins, eg. a 5V logic value from a non-standard JTAG programmer.

I was more concerned about the VCCIO voltage, so I will go with +2.5V on pin G4 (VCCIO Bank 9) of the device.

I had a further look at the handbook, and did not see any problems with using 2.5V for the JTAG.
