Flowkit and 3.3V (dsPIC33) devices

Postby kersing » Sun Jan 08, 2012 11:20 pm

The flowkit documentation does not mention anything about 3.3V device (in)compatibility, looking at the circuit diagram I fear the worst, but just to be sure:

Is Flowkit compatible with 3.3V devices on pins NOT 5V tolerant? (Like pin 4 & 5 of the dsPIC33GJ128GP802)

Hello,

Our EB064 dsPIC programmer has ICD built in which works at 3.3 or 5V.

The Flowkit ICD tool only works at 5V so you will need to use 5V tolerant I/O if possible. You may get away with using the Flowkit on non 5V tolerant pins as the current used is minimal but I cannot guarantee that the pins will survive.

Hi Ben,

Including 3.3V compatibility might be a nice enhancement for the next revision :D For now we'll just use 5V tolerant pins.

Best regards,

Jac
