NJU6635

NJU6635 PRELIMINARY 16-CHARACTER 2-LINE DOT MATRIX LCD CONTROLLER DRIVER s GENERAL DESCRIPTION The NJU6635 is a 1Chip Dot Matrix LCD controller driver for up to 16-character 2-line display with double height function. 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 4/8bit microprocessor. The character generator consists of 9,600 bits ROM and 32 x 5 bits RAM. The standard version ROM is coded with 240 characters including capital and small letter fonts. The 16-common and 80-segment drive up to 16-character 2-line LCD panel which divided two common electrode blocks. The rectangle outlook is very applicable to COG. s PACKAGE OUTLINE NJU6635CH s FEATURES q q q q q q q q q q 16-character 2-line Dot Matrix LCD Controller Driver 4/8 Bit Microprocessor direct Interface Display Data RAM :32 x 8 bits : Maximum 16-character 2line 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 direst accessing to Display Data RAM and Character Generator RAM High Voltage LCD Driver :16-common / 80-segment Duty Ratio :1/16 Duty Maximum Display Cha...
