Hi all,

I've just started playing with the 16F628 and i've got a problem with
unreliable
start-up. Up until yesterday, i've been using a 16F84, and found that it
ran
reliably and started up reliably with virtually any crystal and
capacitor selection.

My problem is that I have tried to run a 16F628 at 32 kHz and 3.3 Volts
(power
consumption critical) and have found that I have to use capacitor values
of close
to 100pF. Before I get shouted at, I know this is what it says in the
data sheet, but
my points are, 1) I never had to with the 16F84's, and 2) The start-up
time is unacceptable
with these capacitors. I am seeing a noticeable delay before the program
starts to run.

Has anyone else noticed this? Have I just been lucky and got good
16F84's in the past?
Is there a solution to my problem?

Thanks

Graham North
