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.
