I looked on the web but can't find any comments on the distribution of PIC watchdog timer periods. i.e. the spec sheet says between 7 and 33ms but what is the standard deviation? Also, what is the typica % variation with temperature. We are building a simple monitoring device and would like to use our boards with the PIC16F628's asleep for most of the time to save power.
