I'm using a 16C71 on a project, but as it is a very old project, I have some
instances of poor electrical design :)  One instance of this has RB5
directly driving a normal radio control servo, which consumes much current
(I believe somewhere around 300mA, but I haven't measured it).  It seems to
work fine with the 16C71, but when I switch my code over to a 16C715, the
chip itself becomes VERY sensitive to lower supply voltages, somewhere
around 5.10V and below.  If I move the servo too fast, the chip often
resets, or sometimes just pauses for a moment, then continues with normal
operation.  I think this is because the servo draws more current when it is
in rapid motion.

I guess my question is more of a request for affirmation, but could the high
current draw directly from the pin be causing this intermittancy?  Have I
possibly damaged the PIC in any way permanently?  I will, of course, add a
transistor to drive the servo, but I guess if there are other problems, or
if this isn't the cause of the intermittancy, I'd like to know what they
might be, anyway.

I'm thinking that maybe the "newer" hardware design of the 16C715 has
resulted in a, shall we say, "more economical" construction and is more
sensitive to out-of-spec conditions than the 16C71.

Thanks,
