The NJU6624A B is a Dot Matrix LCD Controller driver for 12-character 1-line with icon Display in single chip. It contains bleeder resistancegeneral output portkeyscan circuitCR oscillatormicroprocessor Interface circuitinstruction decoder controllercharacter generator ROM/RAMhigh voltage operation common and segment driversand 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 80 kinds of icon on the icon Display area. The 8-common (7 for character1 for icon) and 71-segment drivers operate 12-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. Thereforethe 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 1MHzcommunicates with external MCU. As an outstanding featureNJU6624A/B realizes the horizontal smooth scroll of characters by combination of instructions. The combination of NJU6624A as the Master and NJU6624B as the slave drive the 12-character and 2-line LCD panel or 24-character 1-line in 1/8 duty.
