Preliminary 16-CHARACTER 3-LINE DOT MATRIX LCD CONTROLLER DRIVER s GENERAL DESCRIPTION The NJU6637 is a 1Chip Dot Matrix LCD controller driver for up to 16-character 3-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 1MHz frequency, can be connected directly to serial I/F microprocessor. The character generator consists of 10,200 bits ROM and 8 x 5 bits RAM. The standard version ROM is coded with 255 characters including capital and small letter fonts.
