Manufacturer's part number :


Manufacturer New Japan Radio

New Japan Radio

Description :

The NJU6470 is a Dot Matrix LCD controller driver for 16-character 1-line with keyscan in single chip.

It contains keyscan circuit and input/output ports, bleeder resistance, oscillation circuit, microprocessor interface circuits, instruction decoder controller, character generator ROM/RAM, high voltage operation common and segment drivers.

The microprocessor serial interface circuit which operates by 1 MHz is incorporated.

The character generator ROM consists of 7,680 bits stores 192 kinds of 5 x 8 dots character Font. Each 160 bits CG RAM and Icon display RAM stores 4 kinds of special character displayed on the dot matrix display area and 80 kinds of Icon on the Icon display area. The 18-common and 40-segment drivers operated up to 16-character 1 -line with 80 Icon and static segment LCD display.
