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 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. · 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 - Character Generator ROM (CGROM): 10,080 bits (204 characters×5×8 dots) & (32 characters×5×11 dots) - Character Generator RAM (CGRAM): 64×8 bits (8 characters×5×8 dots) - Display Data RAM (DDRAM): 80×8 bits (80 characters max.) · Low power operation - Power supply voltage range (VDD): 2.7 to 5.5 V - LCD Drive voltage range (VDD-V5): 3.0 to 13.0 V · CMOS process · Programmable duty cycle: 1/8, 1/11, 1/16 · Internal oscillator with external resistor · Low power consumption · 80 QFP or bare chip available
