KS0065B 40CH SEGMENT/COMMON DRIVER FOR DOT MATRIX LCD
INTRODUCTION
64 QFP-1420F
The KS0065B is a LCD driver LSI which is fabricated by low
power CMOS technology. Basically this LSI consists of 20 x 2bit
bi-directional shift register, 20 x 2bit data latch and 20 x 2bit driver.
(refer to Fig 1) This LSI can be used as common or segment driver.
FUNCTION
Dot matrix LCD driver with 40 channel output.
Selects function to use common/segment drivers
simultaneously.
Input / Output signal
- output : 20 x 2 channel waveform for LCD driving
- input : - Serial display data and control signal from the controller LSI.
- Bias voltage (V 1 ~V 6 )
FEATURES
Display driving bias : static~1/5
Power supply voltage : 2.7 ~ 5.5V
Supply voltage for display : 3.0 ~ 13.0V (V LCD =V DD -V EE )
Interface
Driver (cascade connection)
