What is the erase/program endurance for the 16C84? Not what the data book
says but what people actually see. The data book says 100. Is this
conservative or not?

It's been a little while since I did this so the figures may be a whisker
out, (I do have them somewhere) but I conducted a test over 50 hours
reprogramming a PIC84. I gave up eventually coz I figured my hard drive
would wear out before the PIC would. The results were posted on the
I was able to program the same device 1000 times without error.
I think it was David Tait that suggested that I should erase it or change
bit patterns between burns as the same bits may not be damaged if they
aren't set to a different state.
I did this and found that I had my first failure at around 1300 burns.
After 2000 burns I had 3 errors. I still use the same chip today for
development, it's the one with the white liquid paper dot on the top!
Been in backwards with power on more than one occassion too!!
