'[PICLIST] [PIC] RC Oscillator + Prices'

Hi

Two things I wanted to ask about.

One was I'm trying to find a app or design note on RC oscillators. I'd like
to find something
that shows me how to work out what I need. This is obviously on a non
timing critical app
using a 16F84A.  Has anyone got one of these to work using the RC ? I'm
reading through
AN588 right now but a quick skim doesn't seem to show anything so I thought
I'd ask.

Curious about pricing. I picked up 3 of the F84A's for about $5.10 US each.
How does that compare
from the various suppliers in the US?

TNX

Dave

Set your config to RC of course

In NZ I can get the F628 for NZ$6 (~US$3) in tube lots of 25. The
F84A is no longer supported by many trade outlets, but if I really
really really needed one (although I have 1/2 tube left) I could buy
one-offs at retail for $12.89 (Dick Smith) or anywhere from NZ$23
to NZ$25 (RadioSpares). Prices do not include rebatable 12.5% tax
or trade discounts

You should be changing to the F628. Tell 'im Byron. It's cheaper
and has many more features than the F84A

Thanks. That will help when I rummage through my parts bin ;-]

These just happened to be something I could actually grab instead of waiting
for.  That and I needed an excuse to fire up my newly inherited epic
programmer.
For what I want to use these for I just need bare bones cheeeeaaaaap.
Internal RC would be nice too. Other than probes for switch positions
everything
else is just pwm.

Tnx J.

You can check out my list here:

So the 16F628 will help in three respects:

1) Internal RC.
2) Internal hardware PWM
3) Lower cost.

It's the right ticket here.
