NJU6631A PRELIMINARY 16-CHARACTER 1-LINE DOT MATRIX LCD CONTROLLER DRIVER s GENERAL DESCRIPTION The NJU6631A is a 1 Chip Dot Matrix LCD controller driver for up to 16-character 1-line or 8-character 2-line display. It contains microprocessor interface circuits, instruction decoder controller, character generator ROM/RAM and common and segment drivers. The bleeder resistance generates for LCD Bias voltage internally. The CR oscillator incorporates C and R, therefore no external components for oscillation are required. The microprocessor interface circuits which operate 2MHz frequency, can be connected directly to 4bit/8bit microprocessor. The character generator consists of 9,600 bits ROM and 32 x 5 bits RAM.
