Hi,
A brand new pic16f819 fried under my eyes : it was running on my easypic2 development board, with nothing else than leds on its outputs, when I saw the RB6 and RB7 leds dimming and then turning off. After that, I was unable to flash it again (RB6 and RB7 are the programming pins). And all others pins work well...
This chip was brand new, has only a very few cycles of flash writes (a dozen), has never been loaded on its ouptuts, and my board runs perfectly well (I tried after that to flash and run some other pics of p16 & p18 family without any problem).
I fried by myself some pics, but I never saw a pic frying of its own 8-(
As it is not 100% dead, I wonder if it is a defective chip or something else.
Does anybody here did experiment the same issue ?
Thanks !
Bruno
