Single-Chip, Ultra-Low Power
68COM x 294SEG Matrix
Passive Color LCD Controller-Driver
INTRODUCTION
UC1681s is an advanced high-voltage mixed-
signal CMOS IC, especially designed for the
display needs of ultra-low power hand-held
devices.
x Support both row ordered and column
ordered display buffer RAM access.
x Support industry standard 3-wire, 4-wire
serial bus (S9, S8, S8uc) and 8-bit/4-bit
parallel bus (8080 or 6800).
This chip employs UltraChip’s unique DCC
x Special driver structure and gray shade
(Direct Capacitor Coupling) driver architecture to
modulation scheme. Ultra-low power
achieve near crosstalk free images, with well
consumption under all display patterns.
balanced gray shades and vivid colors.
x No power consumption or image quality
In addition to low power COM and SEG drivers,
penalty when used with video rate CSTN
UC1681s contains all necessary circuits for
high-V LCD power supply, bias voltage
generation, timing generation and graphics data
memory.
x Fully programmable Mux Rate, partial
display window, Bias Ratio and Line Rate
allow many flexible power management
options.
Advanced circuit design techniques are
employed to minimize external component counts
www.DataSheet4U.comand reduce connector size while achieving
x Software programmable four temperature
compensation coefficients.
extremely low power consumption.
x Self-configuring 8x charge pump with on-
chip pumping capacitors
MAIN APPLICATIONS
x Cellular Phones and other battery operated
x Flexible data addressing/mapping schemes
to support wide ranges of software models
palm top devices or portable Instruments
and LCD layout placements.
FEATURE HIGHLIGHTS
x Single chip controller-driver for 68x98
matrix C-STN LCD with comprehensive
support for input format and color depth:
12-bit RGB: 4K-color
16-bit RGB: 60.5K-color (dither)
x Support video rate CSTN applications.
x Partial scroll function and programmable
data update window to support flexible
manipulation of screen data.
x Two ID pins plus two programmable ID
flags, totally 4 software-readable ID bits, to
support configurable vender identification.
x Very low pin count (10 pins with S9) allows
exceptional image quality in COG format on
conventional ITO glass.
x Many on-chip and I/O pad layout features to
support optimized COG applications.
x VDD (digital) range: 1.8V ~ 3.3V
VDD (analog) range: 2.5V ~ 3.3V
LCD VOP range:
4.8V ~ 11.8V
x MTP VLCD trimming circuit to support
precise LCD contrast matching
x Available in gold bump dies and COF:
Bump pitch:
38 PM
Bump gap:
Bump surface:
15 PM
> 2369 PM2
