Overview
KS0105 _ INTRODUCTION 32 CH COMMON DRIVER FOR DOT MATRIX LCD 64 QFP KS0105 is a LCD driver LSI which is fabricated by low power CMOS high voltage process technology.
This device consists of timing generator circuit, 32 bit shift register and 32 bit driver.
FUNCTION • Dot matrix LCD common driver with 32 channel output • Input /Output signal - Input: bias voltage (V1, V2, V5, V6, VEE) - Output; 32 channel waveform for LCD driving and segment driver control pulse.
FEATURE • Power supply voltage: +5V ±10% • Supply voltage for display: 0~-5.
5V(V EE) • Applicable LCD duty; selectable 7 kinds (1/8, 1/12, 1/16, 1/24, 1/32, 1/48, 1/64) • Interface COMMON Other KS0105 SEGMENT KS0106 • Oscillator frequency can be set by adjusting external capacitor and resistor • 64 QFP or bare chip available.
