GENERAL DESCRIPTION
The NJU6624C is a Dot Matrix LCD controller driver for 14-character 1-
line with icon display in single chip.
It contains bleeder resistance, general output port, keyscan circuit,
CR oscillator, microprocessor interface circuit, instruction decoder con-
troller, character generator ROM/RAM, high voltage operation com-
mon and segment drivers, and others.
The character generator ROM consisting of 7,840 bits stores 224 kinds
of character Font. Each 1,120 bits CG RAM and Icon display RAM
can store 32 kinds of special character displayed on the dot matrix
display area or 70 kinds of Icon on the Icon display area.
The 8-common (7 for character, 1 for icon) and 70-segment drivers
operate 14-character 1-line with 70 Icon LCD display and LED driver
drives 4 LED which can use like as indicator.
The 16th display contrast control function is incorporated. Therefore,
the contrast adjustment is operated easily by only simple power sup-
ply circuit on-chip.
The complete CR oscillator requires no external components.
The serial interface which operates by 1MHz, communicates with ex-
ternal MCU.
