DOT MATRIX LCD CONTROLLER WITH 17-DOT COMMON DRIVER AND 80-DOT

SEGMENT DRIVER

GENERAL DESCRIPTION

The MSM6555B-xx is a dot matrix LCD controller with 17-dot common driver and 80-dot

segment driver comprising a display RAM, character generation ROM, LCD bias generation

circuit and control circuit.

The LCD driving bias generation circuit incorporated in the MSM6555B-xx allows LCD bias

voltage to be obtained merely by providing a specified capacitance externally.

The MSM6555B-xx can display the arbitrator (arbitrary character) patterned on the LCD panel.
