MSTN LCD DRIVER IC UC1611s

Single-Chip, Ultra-Low Power
160COM x 256SEG Matrix
Passive LCD Controller-Driver
INTRODUCTION
UC1611s is an advanced high-voltage
mixed-signal CMOS IC, especially designed for
the display needs of ultra-low power hand-held
devices.
UC1611s employs UltraChips unique DCC
(Direct Capacitor Coupling) driver architecture
and LRM (Line Rate Modulation) gray-shade
modulation scheme to achieve near crosstalk free
images, with well balanced gray shades.
In addition to low power SEG and COM drivers,
UC1611s 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.
MAIN APPLICATIONS
Cellular Phones, Smart Phones, PDA, and
other battery-operated palmtop devices
and/or portable instruments.
FEATURE HIGHLIGHTS
Single-chip controller-driver supports
160x256 STN LCD, 16-shade-per-pixel with
gamma compensated modulation.
Soft-ICON: Partial scroll function to support
programmable graphics ICON or scroll bar.
Support both row ordered and column
ordered display buffer RAM access
Support industry standard 4-wire, 3-wire,
and 2-wire serial buses (S8, S9, I2C), and
16- /8- /4-bit parallel buses (8080 or 6800).
Special driver structure and gray shade
modulation scheme produce near crosstalk
free image, with low power consumption for
all display patterns.
Fully programmable Mux Rate, partial
display window, Bias Ratio, and Line Rate
allow many flexible power management
options.
4 software programmable frame rates (25Hz,
30Hz, 35Hz, and 40Hz). Support the use of
fast Liquid Crystal material for speedy LCD
response.
4 software-programmable temperature
compensation coefficients.
On-chip Power-ON Reset and Software
RESET command make RST pin optional.
Self-configuring 11x charge pump with
on-chip pumping capacitor requires only 5
external capacitors to operate.
Flexible data addressing/mapping schemes
to support wide ranges of software models
and LCD layout placements.
