MSTN LCD DRIVER IC UC1610i

Single-Chip, Ultra-Low Power
128COM x 160SEG Matrix
Passive LCD Controller-Driver
INTRODUCTION
UC1610i is an advanced high-voltage mixedsignal
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, with well
balanced gray shades.
In addition to low power COM and SEG drivers,
UC1610i 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 and other battery operated
palm top devices or portable Instruments
FEATURE HIGHLIGHTS
Single chip controller-driver for 128x160
matrix STN LCD with 4 gray shades.
One software readable ID pin to support
configurable vender identification.
Partial scroll function and programmable
data update window to support flexible
manipulation of screen data.
Support both row ordered and column
ordered display buffer RAM access
Support industry standard 2-wire, 3-wire,
4-wire serial bus (I2C, S9, S8, S8uc) and
8-bit/4-bit parallel bus (8080 or 6800).
Special driver structure and gray shade
modulation scheme. Consistent low power
consumption under all display patterns.
Fully programmable Mux Rate, partial
display window, Bias Ratio and Line Rate
allow many flexible power management
options.
Four software programmable frame rates
up to 130Hz. Support the use of fast Liquid
Crystal material for speedy LCD response.
Software programmable 4 temperature
compensation coefficients.
On-chip Power-ON Reset and Software
RESET command, make RST pin optional.
Self-configuring 8x charge pump with onchip
pumping capacitors. Only 3 external
capacitors are required to operate.
Flexible data addressing/mapping schemes
to support wide ranges of software models
and LCD layout placements.
Very low pin count (9~10 pins with S9 or I2C)
allows exceptional image quality in COG
format on conventional ITO glass.
Many on-chip and I/O pad layout features to
support optimized COG applications.
