PRELIMINARY SPECIFICATION
64COM/128SEG DRIVE FOR DOT MATRIX LCD
INTRODUCTION
KS0708 is a single-chip LCD driver LSI for liquid crystal dot-matrix graphic display systems. It incorporates
192 driver circuit for 64 commom and 128 segment and 64x128-bit bit-map RAM. It is capable of interfac-
ing with the microprocessor, accepting 8-bit parallel display data directly from it, and storing data in an
onechip Display Data RAM. And it generates internal signals for using LCD driving independent of micro-
processor clock.
FEATURES
¡Ü 64-Channel COMMON & 128-Channel SEGMENT Driver for DOT matrix LCD
¡Ü On-chip display data RAM : 64 X 128 = 8192bits
¡Ü Display data is stored in display data RAM from MPU
- RAM bit data : ON(1), OFF(0)
¡Ü Internal timing generator circuit for dynamic display
¡Ü 8-bit parallel bi-directional data bus
¡Ü Applicable LCD duty : 1/64
¡Ü Power supply voltages : Power supply voltage range : 4.5 ~ 5.5 V(VDD)
LCD Driving voltage range : 8.0 ~ 17.0 V(VLCD = VDD - VEE)
¡Ü Wide operating temperature range : Ta = -30 ¡É ~ 85¡É
¡Ü High Voltage CMOS process
¡Ü Package : available bumped chip
