Yes, I should have mentioned this. Some of these displays do not have a
character generator, which should be implemented in software.
[ For some applications this may be an advantage, because it allows
limited graphic capabilities. ]

Thanks for the tip, interesting chip.

micro to the '6955 and then the '6955 to the actual display is more
complicated than using one of the Avago displays.
But, I am not concerned about the SW development tasks you mentioned.
(That's what I do every day for a living.)
For somebody without a software background and/or who wants to get it
running quickly, this may be a better choice.
