com KS0108B INTRODUCTION 64CH SEGMENT DRIVER FOR DOT MATRIX LCD 100 QFP The KS0108B is a LCD driver LSl with 64 channel output for dot matrix liquid crystal graphic display system.
This device consists of the display RAM, 64 bit data latch 64 bit drivers and decoder logics.
It has the internal display RAM for storing the display data transferred from a 8 bit micro controller and generates the dot matrix Iiquid crystal driving signals corresponding to stored data.
The KS0108B composed of the liquid crystal display system in combination with the KS0107B (64 common driver) FEATURES • Dot matrix LCD segment driver with 64 channel output • Input and Output signal - Input: 8 bit parallel display data Control signal from MPU Splitted bias voltage (V1R, V1L, V2R, V2L, V3R.
V3L, V4R, V4L) - Output: 64 channel waveform for LCD driving.
• Display data is stored in display data RAM from MPU.
• Interface RAM - Capacity: 512 bytes (4096 bits) - RAM bit data: RAM bit data = 1:ON RAM bit data- = 0:OFF • Applicable LCD duty: 1/32~1/64 • LCD driving voltage: 8V~17V(V DD-VEE) • Power supply voltage: + 5V ±10% Driver COMMON KS0107B SEGMENT Other KS0108B Controller MPU • High voltage CMOS process.
• 100QFP and bare chip available.
