TECHNICAL DATA

0066 DOT MATRIX LCD CONTROLLER &DRIVER

The KK 0066 is a dot matrix liquid crystal display controller & driver LSI that displays alphanumeric, characters

and symbols.

It drives dot matrix LCD under microcomputer control. All functions needed for dot matrix LCD drive are

internally provided on one chip.

FEATURES

? Internal Memory

- Character Generator ROM: 8320 bits - Character Generator RAM: 512 bit

- Display Data RAM: 80 x 8 bits for 80 digits ? Internal automatic reset circuit at power ON ? Internal oscillation circuit

? Power Supply Voltage: +5V ± 10%

? LCD Driving Voltage for display: 0 ~ -5V(V 5) ? Duty factor selection (selected by programs) 1/8 duty: 5 x 7 dots format 1 line, 1/11 duty: 5 x 10 dots format 1 line 1/16 duty: 5 x 7 dots format 2 line ? Bare chip available

? Pin-to-Pin replacement for KS0066, HD44780, SED1278

FUNCTION

? Character type dot matrix LCD driver & controller ? Internal driver: 16 common and 40 segment signal output

? Display character format: 5 x 7 dots + cursor, 5 x 10 dots + cursor

? Easy interface with a 4-bit or 8-bit MPU ? Display character pattern:
