Single-Chip, Ultra-Low Power
68COM x 96SEG Matrix
Passive LCD Controller-Driver
INTRODUCTION
UC1503t 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 UltraChips unique DCC (Direct
Capacitor Coupling) driver architecture to achieve
near crosstalk free images.
In addition to low power COM and SEG drivers,
UC1503t contains all necessary circuits for
high-V LCD power supply, bias voltage generation,
temperature compensation, 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.
MAIN APPLICATIONS
Cellular Phones, and other battery operated
palm top devices or portable Instruments
FEATURE HIGHLIGHTS
Single chip controller-driver for 68x96
graphics STN LCD panels.
Support both row-ordered and columnordered
display buffer RAM access.
Support industry standard 3-wire serial buses
(S9).
Ultra-low power consumption under all
display patterns.
Fully programmable Mux Rate, partial display,
Bias Ratio and Frame Rate allow many
flexible power management options.
Software programmable frame rates at 68, 73,
78 and 83 Hz
Four software programmable temperature
compensation coefficients
Self-configuring 7-x charge pump with onchip
pumping capacitors. Only 3 external
capacitors to operate.
On-chip Power-ON Reset and Software
RESET commands, make RST pin optional.
Very low pin count (9~10-pin) allows
exceptional image quality in COG format on
conventional ITO glass.
Flexible data addressing/mapping schemes
