I would suggested finding a controller for it. It will relief a lot of processing from the CPU. OKI and Rohm used to make them. It has been a while since I look at those. Why do you want to use a graphic LCD without a controller at the first place? With a LCD controller, even a 8051 will seem very fast.

The price difference between a display with and without a built in controller
is about $10 to $15 and for example the Sharp mcu LH75401 is about $13

this makes for a better overall solution and smaller footprint

also mixing graphics and text doesn't seem to work with for example the
SED13XX series using the built in character generator

NEVER REINVENT THE WHEEL !!!!!!!!!!!!!!!!!!!!!!!!!!

Except if your main target is to make a graphic LCD controller, i really advise you to get a module with a built-in controller chip. It will save you a hill of a headache. I strongly recommend a T6936 based one, since it accepts mixing graphics and text on screen easily.

Hope this helps.

If you want to do Graphics, you need a build-in controller. If just TEXT, any 8051 PIC etc will do.

Try Motorola DragonBall series (68K or ARM core):
such like as MC68EZ328 (68K core), build-in LCD Controller
(software programmable up to 640x512)
and the list price is under U$5.
If you need more performance,
try MC9329MXL/MC9328MX1 (ARM920T core),
list price will be under U$10~15.
