The A31W33128 is a CMOS LCD driver, which has 128 segment, and 17 or 33 common graphic display. It has 80/68-series
8 bit parallel and serial interface capability for operating with general CPU. The internal 65 x 128 display data RAM makes
the display of both graphics and characters possible. Besides the general LCD driver features, it has on chip LCD bias
divider circuit such that minimize external component required in system application.
