UC1682
Single-Chip, Ultra-Low Power
80COM x 312SEG Matrix
Passive Color LCD Controller-Driver
I
UC1682 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, with well
balanced gray shades and vivid colors.
In addition to low power COM and SEG drivers,
UC1682 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.

Support industry standard 3-wire, 4-wire
serial bus (S9, S8, S8uc) and 8-bit/4-bit
parallel bus (8080 or 6800).
Special driver structure and gray shade
modulation scheme. Ultra-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.
Software programmable frame rates up to
250Hz. Support the use of fast Liquid
Crystal material for speedy LCD response.
Software programmable four temperature
compensation coefficients.
On-chip Power-ON Reset and Software
Reset command, make RST pin optional.
Self-configuring 10x charge pump with on-
chip pumping capacitors. Only 2/3 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)
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.
