32COM/60SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD

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
24 characters or 2 line
24

characters with 5
7 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 5
7 dots )

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

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

• Maximum display characters

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

-. 2 line, 1/32 duty, 5
7 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: +5V10%, +3V20%

• Supply voltage for display: -5V

• Package outline: 118 TAB or bare chip available.
