26COM/84SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD
RockWorks Technology Corp.
For logical circuit(+3V,+5V)
0V (GND)
Bias voltage level for LCD driving
Reference voltage input to generate V0
Segment signal output for LCD drive
Common signal output for LCD drive
Common signal output for LCD drive
When use internal oscillator, connect external
Rf resistor.
If external clock is used, connect it to OSC1、
OSC2 is floating.
To use the voltage converter (2 times/ 3
times), these pins must be connected to the
external capacitance.
(Please see page 36 for more detail)
