According to the new Digi-Key catalog, the PIC 16C92X is an
8 bit Micro with an LCD driver built-in.  Has anyone had any
experience with this device?

I am working on a project with a 16F84 that will hopefully
output to an LCD.  Would I be better off to use the 16C92X and
avoid all the extra hardware to do the same thing with the
16F84?  I'm just a newbie at this, so the answer may be somewhat
obvious to others...

Thanks for any help.

Fred.
