TECHNICAL DATA
40 Channel Segment / Common Driver For Dot Matrix LCD
KK0065
The KK0065 is a LCD driver LSI which is fabricated by low power CMOS technology. Basically this LSI consists of 20 x 2 bit bi-directional shift register, 20 x 2 bit data latch and 20 x 2 bit driver. This LSI can be used a common or segment driver.
FEATURES
* Display driving bias: static -1/5 * Power supply voltage: +5V 10%, +3V 10% * Supply voltage for display: 0 ~ -5V(VEE) * Interface
FUNCTIONS
* Dot matrix LCD driver with 40-channel output. * Selectable 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 pulse from the controller LSI. * Bias voltage (V1-V6)
