16F876A chip failures
Has any members here experience pic chip failures?
We have been experiencing an occasion failure of the 876A pic, where the lcd winds up displaying on the top line - black bars. the pic might have been working for months perfectly, and this failure suddenly happen. we haven't been able to identify particular circumstances, but the pic is "toast".
the pic is in a board the basically reads an resistance ladder value and displays the information onto an optrex lcd 2x16 display. the hardware and software have been relatively stable and we have around 50 or so out in the field.
we have had a couple fail over the past few month while with this problem. while not overly alarming, it is of concern since we don't really have a handle on the problem.
just wondering if any other members have had seen or experience this problem?
