14-Character 1-Line Dot Matrix LCD Controller Driver with Smooth Scroll

Manufacturer's part number :

NJU6624CFG1

Manufacturer New Japan Radio

New Japan Radio

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 controller, character generator ROM/RAM, high voltage operation common 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 60 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 60 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 supply circuit on-chip.

The complete CR oscillator requires no external components. The serial interface which operates by 1MHz, communicates with external MCU.
