LC450029PKB
CMOS IC
1/4 and 1/3-Duty General-Purpose
LCD Display Driver
http://onsemi.com
Overview
The LC450029PKB is 1/4 duty and 1/3 duty general-purpose microcontroller-controlled LCD drivers that can be
used in applications such as frequency display in products with electronic tuning. In addition to being capable to
drive up to 208 segments directly. The internal oscillation circuit helps to reduce the number of external resistors and
capacitors required. The chip shape is slim for COG (Chip-On-Glass) implementation. The operating temperature
range is from -40°C to +105°C
Application
• Car or general consumer electronic LCD display equipment.
Features
• Selectable 1/4-duty or 1/3-duty drive by the serial control data
When 1/4-duty: Capable of driving up to 208 segments
When 1/3-duty: Capable of driving up to 159 segments
• 1/3-bias only
• Serial data input supports CCB* format communication with the system controller. (For 5V operation only)
• The power-saving mode is selectable by the serial control data, and supports low power consumption.
• Adjustable the frame frequency of the common and segment output waveforms by the serial control data
• Selectable the internal oscillator operating or external clock operating mode by the serial control data
• High generality, since display data is displayed directly without the intervention of a decoder circuit.
• The INH pad allows all LCD segments to be forced to the off state.
• With a built-in oscillator circuit (External resistors and capacitors are unnecessary.)
• The stability of the LCD bias voltage is high by a built-in LCD bias generator with voltage-follower buffers.
• Shipping form: Chip with Au bumps in tray.
• Allowable operating voltage (VDD, VDDI)
: +4.5V to +6.0V
• Allowable wide operating temperature ranges
: -40°C to +105°C

Control Data Functions
(1) EXF … Ratio of dividing frequency in external clock operating mode setting control data
This control data sets the ratio of dividing frequency of the external clock which input into the OSCI pad, when the
external clock operating mode (OC=“1”) is set. However, this data is effective only when external clock operating
mode (OC= “1”) is set. The frame frequency is adjustable by setting EXF, FC0 to FC2 and OC.

Display Control and the INH Pad
Since the LSI internal data (1/4 duty : the display data D1 to D208 and the control data, 1/3 duty : the display data D1 to
D159 and the control data) is undefined when power is first applied. Applications should set the INH pad low at the
same time as power is applied to turn off the display (This sets the S1 to S53 and COM1 to COM4 pads the VSS level.)
and during this period send serial data from the controller. The controller should then set the INH pad high after the data
transfer has completed. This procedure prevents meaningless display at power on. VDD and VDDI are connected with
the same power supply. The timing of turn on and turn off for VDD and VDDI should be same time.

Notes on Controller Transfer of Display Data
When using the LC450029PKB in 1/4 duty, applications transfer the display data (D1 to D208) in four operations, and
in 1/3 duty, they transfer the display data (D1 to D159) in three operations. In either case, applications should transfer
all of the display data within 30ms to maintain the quality of displayed image.

The Notes on Use
Important things for stability operation of IC are shown as follows. The contents indicated below do not guarantee IC
operation and the characteristic. Moreover, the example of an application circuit written in these specifications is for
explaining internal operation and usage. Therefore, please perform the design in consideration of the specification of
operation and terms and conditions in the actual LCD panel.
(1) The design of power supply
All power supply pads are connected to the power supply, and do not set open.
(2) ITO (Indium Tin Oxide) wiring
By designing the wire of power supply (VDD, VDDI, VSS) wide and short, make the parasitic resistance of ITO
wiring into the minimum.
(3) Signal wiring and connection
The DUMMY pad does not connect to anywhere, and sets open.
(4) Processing of unused input pad
For CMOS process, if an input pad is in open state, operation of IC may become unstable, or unnecessary power
supply current may flow through it. Please be sure to connect the empty pad of a logic input to VSS.
(5) The measure against shading
The optical irradiation to IC causes the mis-operation of IC. When IC is implemented, take the measures against
shading about the surface, back and side of IC.
