KS0071B
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 57 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 57 dots )
-. Character generator RAM : 512 bits ( 8 patterns for 57 dots )
-. Display data RAM : 640 bits ( 808 bits for 80 characters )
Maximum display characters
-. 1 line, 1/16 duty, 57 dots + cursor, 24 characters.
-. 2 line, 1/32 duty, 57 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.
