MSTN LCD DRIVER IC UC1701x

Single-Chip, Ultra-Low Power
65COM by 132SEG
Passive Matrix LCD Controller-Driver
INTRODUCTION
UC1701x 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.
In addition to low power column and row drivers,
the IC 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 palm top devices or
portable Instruments
FEATURE HIGHLIGHTS
Single chip controller-driver support 65x132
graphics STN LCD panels.
Support both row ordered and column
ordered display buffer RAM access.
Support industry standard 8-bit parallel bus
(8080 or 6800 mode) and 4-wire serial bus
(S8) interface.
Ultra-low power consumption under all
display patterns.
Fully programmable Mux Rate and Bias
Ratio allow many flexible power
management options.
7-x internal charge pump with on-chip
pumping capacitor requires only 3 external
capacitors to operate.
On-chip Power-ON Reset and Software
RESET commands, make RST pin optional.
Very low pin count (10-pin) allows
exceptional image quality in COG format on
conventional ITO glass.
Flexible data addressing/mapping schemes
to support wide ranges of software models
and LCD layout placements.
