LC75824E, 75824W
1/4 Duty General-Purpose LCD Display Driver
Overview
The LC75824E and LC75824W are 1/4 duty general-
purpose LCD display drivers that can be used for
frequency display in electronic tuners under the control of
a microcontroller. In addition to being able to directly
drive up to 204 LCD segments, the LC75824E and
LC75824W can also control up to 12 general-purpose
output ports.
Features
• Support for 1/4 duty 1/2 bias or 1/4 duty 1/3 bias drive
of up to 204 segments under serial data control
• 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 general-purpose output port functions
• Serial data control of the normal mode current drain
• High generality since display data is displayed directly
without decoder intervention.
• The INH pin can force the display to the off state.
• RC oscillator circuit

Function
Segment outputs for displaying the display data transferred by serial data
input. Pins S1/P1 to S12/P12 can be used as general-purpose output ports
when so specified by the control data.
Common driver outputs.
The frame frequency fO is given by: fO = (fOSC/512) Hz.

OSC
60
Oscillator connection. An oscillator circuit is formed by connecting an external
resistor and capacitor to this pin.
CE 62
Serial data transfer inputs.
CE: Chip enable
CL 63 These pins are connected to the CL: Synchronization clock
microcontroller.
DI: Transfer data

H
Display off control input
• INH = low (VSS) .......Display forced off
Pins S1/P1 to S12/P12 = low (These pins are forced to
the segment output port

function and held low.)
L
S13 to S51 = low
COM1 to COM4 = low
• INH = high (VDD)......Display on
Note that serial data transfers can be performed when the display is forced off.
VDD1
