KS0066U 16COM / 40SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD INTRODUCTION
80 QFP-1420C
KS0066U is a dot matrix LCD driver & controller LSI whichis
fabricated by low power CMOS technology.
It can display 1or 2 lines with the 5Г—8 dots format or 1 line
with the 5Г—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: 5Г—8 dots format (208 kinds) & 5Г—11 dots format (32 kinds). The Special character pattern is directly programmable by the Character Generator RAM. A customer character pattern is programmable by mask option. Programmable Driving Method by the same character font mask option: Display Waveform A-type and B-type It can drive a maximum at 80 characters by using the KS0065B or KS0063B externally. Various instruction functions. Built-in automatic power on reset. FEATURES Internal Memory
