INTRODUCTION

The KS0071B is a dot matrix LCD controller & driver LSI which is fabricated by low power CMOS technology, designed to drive a split screen dot matrix LCD display of 1 line X 24 characters or 2 line X 24 characters with 5X7 dots format.

FEATURES

? Character type dot matrix single chip LCD controller & driver

? High voltage LCD driver 32 common and 60 segment signal output.

? Easy interface with a 4 bit or 8 bit MPU.

? Internal memory

-. Character generator ROM : 8400bits ( 240 characters for 5x7 dots )

-. Character generator RAM : 512 bits ( 8 patterns for 5x7 dots )

-. Display data RAM : 640 bits ( 80x8 bits for 80 characters )

? Maximum display characters

-. 1 line, 1/16 duty, 5x7 dots + cursor, 24 characters.

-. 2 line, 1/32 duty, 5x7 dots + cursor, 24 characters .

? A customer character pattern can be programmable by mask option.

?. The special character pattern can be programmable by character generator RAM directly.

? It is possible to read both character generator and display data RAM from MPU.

? Useful 11 code instruction set

? Automatic power on reset function

? On chip generation of LCD supply voltage from voltage doubler ( external supply also possible )

?.Voltage doubler generates about double from single power supply ( 5V)

? High contrast display can be performed though the simple power supply circuits.

? On chip oscillator requires external resistor ( external clock also possible )

? Power supply voltage: +5V ±10, +3V ±20

? Supply voltage for display: -5V

? Package outline: 118 TAB or bare chip available.
