UC1602i
Single-Chip, Ultra-Low Power
Passive Matrix LCD Controller-Driver
INTRODUCTION
UC1602i is an advanced high-voltage mixed-
signal CMOS IC, especially designed for the
display needs of ultra-low power hand-held
devices.
In addition to low power column and row drivers,
these ICs contain 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 or Smart Phones
Pagers or other battery operated
messaging devices
Battery Powered Portable Instruments
FEATURE HIGHLIGHTS
Supports I
2C 2-wire serial interface and 8-
bit parallel bus interface.
Ultra-low power LCD controller-driver with
built-in display RAM and timing generator to
support compact LCD module using as few
as 5 pins.
VDD2/3 voltage range: 2.4V ~ 3.3V
VDD1 voltage range: 1.8V ~ 3.3V
LCD VOP range:
4.5V ~ 10.5V
6x, built-in self-configuring, charge pump
allows the use of low VDD while produce
high VLCD for driving LCD.
On-chip charge pump pumping capacitors
requires only 3 external capacitors.
Two multiplexing rates: 1/65, 1/49.
Four temperature compensations.
Support both high speed parallel interfaces
and compact serial interfaces.
Flexible data addressing/mapping schemes
to support wide ranges of software models
and LCD layout placements.
