NJU6631A

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. The standard version ROM is coded with 192 characters including capital and small letter fonts. The 16-common and 40-segment drives up to 16character 1-line LCD panels which divided two common electrode blocks. The rectangle outlook is very applicable to COG or Slim TCP. s PACKAGE OUTLINE NJU6631ACH s FEATURES q q q q q q q q q q q q q q q q q q 16-character 1-line Dot Matrix LCD Controller Driver 4/8 Bit Microprocessor Direct Interface Display Data RAM - 16 x 8 bits : Maximum 16-character 1-line Display Character Generator ROM - 9,600 bits : 240 Characters for 5 x 8 Dots Character Generator RAM - 32 x 5 bits : 4 Patterns(5 x 8 Dots) Microprocessor can access to Display Data RAM and Character Generator RAM High Voltage LCD Driver : 16-common / 40-segment Duty Ratio : 1...
