Single-Chip, Ultra-Low Power 128COM x 240SEG Matrix Passive LCD Controller-Driver

INTRODUCTION
UC1608 is an advanced high-voltage mixed signal CMOS IC, especially designed for the
display needs of ultra-low power hand-held devices. This chip employs UltraChip’s unique DCC
(Direct Capacitor Coupling) driver architecture to achieve near crosstalk free images.
In addition to low power COM and SEG drivers, UC1608 contains all necessary circuits for high-V
LCD power supply, bias voltage generation, timing generation and graphics data memory.
Advanced circuit design techniques are employed to minimize external component counts
and reduce connector size while achieving extremely low power consumption.
