12-Character 4-Line Dot Matrix Low Power
LCD Controller Driver with key Scan Function
GENERAL DESCRIPTION
The NJU6475B is a Dot Matrix LCD Controller Driver for
12-character 4-line with Icon display in single chip. It contains
voltage converter, voltage regulator, bleeder resistance, CR
oscillator, instruction decoder, character generator ROM/RAM,
high voltage operation controller/driver and key scan circuit.
The voltage
converter generates (about 8V) from the
supply voltage (3V) and regulated by the regulator. The bias
level of LCD driving voltage is generated of high value bleeder
resistance and the buffer amplifier matches the
impedance. 16-step contrast control function is incorporated
for its adjustment. Therefore, simple power supply circuit and
easy contrast adjustment are available. The complete CR
oscillator is incorporated without external components for
oscillation circuit. The microprocessor interface circuit which
operates by 1MHz, can be selected serial interface.
The character generator ROM consisting of 10,080bits stores
252 kinds of character Font.
Each 160bits CG RAM and Icon display RAM can story
4 kinds of special character to display on the dot matrix
display area or 128 kinds of Icon on the display area.
