NJU6420B 16-CHARACTER 2-LINE DOT MATRIX LCD CONTROLLER DRIVER

The NJU6420B is a 1 Chip Dot Matrix LCD Controller driver for up to 16-character 2-line Display It contains voltage converterbleeder resistanceCR oscillatormicroprocessor Interface circuitsinstruction decoder controllercharacter generator ROM/RAM and high voltage operation common and segment drivers. The voltage converter and bleeder resistance generates about twofold voltage (10V or 6V) and bias voltage for LCD driving waveform internally from single power supply (5V or 3V). Consequentlyhigh-contrast Display CAN be performed though the simple power supply circuits. The resistance and capacitance for CR oscillation circuits are incorporatedtherefore no external components for the oscillation circuits are required. The Microprocessor Interface circuits which operate by 2MHz frequencycan be connected directly to 4/8bit Microprocessor The character generator consists of 9,600 bits ROM and 64 bytes RAM. The standard version ROM is coded with 240 characters including capital and small letter fonts and some of Japanese fonts. The high voltage operation 32-common and 40-segment drivers operate up to 13.5V or 12Vand drive up to 16-character 2-line LCD panels which divided four common electrode blocks.
