I found this:
http://www.datasheetarchive.com/search.php?q=T6A04
First pdf is the required datasheet.

Bottom project is using said controller with a link to source code.
While on topic;
A 5.7" 320x240 colour TFT with a built-in controller. This is the first TFT I've come encountered with built-in controller+ram. Pitty the interface is a little too complex for small projects.
