LC75833E, 75833W, 75833JE
1/3 Duty General-Purpose
LCD Display Drivers
Overview
Package Dimensions
The LC75833E, LC75833W, and LC75833JE are 1/3-duty
general-purpose LCD display drivers that can be used for
frequency display in electronic tuners under the control of
a microcontroller. The LC75833E and LC75833W can
drive an LCD with up to 105 segments directly, the
LC75833JE can drive an LCD with up to 93 segments
directly. The LC75833E and LC75833W and LC75833JE
can also control up to 8 general-purpose output ports.
Since the LC75833E, LC75833W, and LC75833JE use
separate power supply systems for the LCD drive block
and the logic block, the LCD driver block power-supply
voltage can be set to any voltage in the range 2.7 to 6.0
volts, regardless of the logic block power-supply voltage.

Features
unit: mm
3163A-SQFP48
• Supports both 1/3 duty 1/2 bias and 1/3 duty 1/3 bias
LCD drive under serial data control.
LC75833E, LC75833W:
up to 105 segments
LC75833JE:
up to 93 segments
(without the S12, S23, S24, S35 segment output pins
from the LC75833E, LC75833W)
• Serial data input supports CCB format communication
with the system controller.
• Serial data control of the power-saving mode based
backup function and all the segments forced off function
• Serial data control of switching between the segment
output port and the general-purpose output port
functions
• High generality, since display data is displayed directly
without decoder intervention.
• Independent VLCD for the LCD driver block (VLCD can
be set to any voltage in the range 2.7 to 6.0 volts,
regardless of the logic block power-supply voltage.)
• The INH pin can force the display to the off state.
• RC oscillator circuit

Also note that when the general-purpose output port function is selected, the output pins and the display data will
have the correspondences listed in the tables below.

The INH pin and Display Control
Since the LSI internal data (the display data and the control data) is undefined when power is first applied, applications
should set the INH pin low at the same time as power is applied to turn off the display (LC75833E, LC75833W: This
sets the S1/P1 to S8/P8, S9 to S35, and COM1 to COM3 to the VSS level. LC75833JE: This sets the S1/P1 to S8/P8, S9
to S11, S13 to S22, S25 to S34, and COM1 to COM3 to the VSS level.) and during this period send serial data from the
controller. The controller should then set the INH pin high after the data transfer has completed. This procedure prevents
meaningless displays at power on. (See Figure 3.)
Notes on the Power On/Off Sequences
Applications should observe the following sequence when turning the LC75833E, LC75833W, and LC75833JE power
on and off.
• At power on: Logic block power supply (VDD) on → LCD driver block power supply (VLCD) on
• At power off: LCD driver block power supply (VLCD) off → Logic block power supply (VDD) off
However, if the logic and LCD driver block use a shared power supply, then the power supplies can be turned on and off
at the same time.

Notes on Controller Transfer of Display Data
Since the LC75833E, LC75833W, and LC75833JE accept display data divided into three separate transfer operations,
we recommend that applications transfer all of the display data within a period of less than 30 ms to prevent observable
degradation of display quality.
