KS0066U

16COM / 40SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD

INTRODUCTION

KS0066U is a dot matrix LCD driver & controller LSI whichis

fabricated by low power CMOS technology.

It can display 1or 2 lines with the 5

×8 dots format or 1 line

with the 5

×11 dots format.

FUNCTIONS

• Character type dot matrix LCD driver & controller.

• Internal driver: 16 common and 40 segment signal output.

• Easy interface with 4-bit or 8-bit MPU.

• Display character pattern: 5

×8 dots format (208 kinds) & 5×11 dots format (32 kinds).

• The Special character pattern is directly programmable by the Character Generator RAM.
