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 I2C 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.

Description
MAIN POWER SUPPLY
VDD1 supplies for display data RAM and digital logic, VDD2 supplies for
VLCD/VB generator, VDD3 supplies for VREF and other analog circuits.
VDD2/VDD3 should be connected to the same power source. But VDD1 can
be connected to a source voltage no higher than VDD2/VDD3.
In COG applications, always use separate ITO traces for VDD1, VDD2 and
VDD3 to reduce noise coupling.
Ground. In COG applications, use separate ITO traces to connect VSS
and VSS2 to the separate GND pins or to the shared GND pin and
minimize both ITO resistance.
LCD POWER SUPPLY
LCD Offset Voltages. Connect two CB capacitors between VB+ to VB0+
and VB0– to V B–. For optimum operation result, minimize the ITO trace
resistance of these nodes.
Place CB1 and CB0 on the FPC or COF to reduce I/O pin count by 4.
Main LCD Power Supply. When internal VLCD is used, connect these
pins together. When external VLCD source is used, connect external
VLCD source to VLCD-IN pins and leave VLCD-OUT pins open.
A by-pass capacitor CL should be connected between VLCD and VSS2.
Minimize the ITO trace resistance in COG applications.
NOTE
Recommended capacitor values:
CB: 150~500x LCD load capacitance or 1.0uF (VBR > 3V), whichever is higher.
CL: 20~50x LCD load capacitance or 0.2uF (VBR > VLCD+1V), whichever is higher.
