Yes he is using a Toshiba based controller - this is what the CY325 talks to. I guess the main advantage of using the CY325 to me is the reduction in the number of control lines needed (3 vs ~ 11) David V.

But he already has a T6963 controller ... I am considering an LCD (with such a controller) and a PIC interface to a 16C72 or the same as he's using. I have an ICE PIC Jr which emulates a 16C74 at the moment and can handle 16C72. I have not really started it yet since we're evaluating off the shelf serial LCDs (text) and haven't decided whether to migrate to an equivalent 4x20 sized graphic display. If it were a 16C74 target (overkill) or the 16F877 (which has PSP I believe) I would consider connecting the LCD T6963 interface specifically to the parallel slave port (CS\ etc) after checking the timing specifications. On the 16C72 I have considered (a little!) driving the control strobes in software but this may or may not be too slow.
