I don't know what chip is onboard, but as a display it is completely compatible with the Hitachi HD44780 based LCD displays sold at Dick Smith, Jaycar, and everywhere else, so if you can talk to them, you can talk to this. I actually use the exact same routines.

Actual visible display dimensions are 260x71mm.



I have also found the complete datasheet on my hard drive and upped it to Megaupload:
