1/3 Duty LCD Display Drivers with Key Input Function
Overview
The LC75863E and LC75863W are 1/3 duty LCD display
drivers that can directly drive up to 75 segments and can
control up to four general-purpose output ports. These
products also incorporate a key scan circuit that accepts
input from up to 30 keys to reduce printed circuit board
wiring.
Features
• Key input function for up to 30 keys (A key scan is
performed only when a key is pressed.)
• 1/3duty - 1/2bias and 1/3duty - 1/3bias drive schemes
can be controlled from serial data (up to 75 segments).
• Sleep mode and all segments off functions that are
controlled from serial data.
• Segment output port/general-purpose output port
function switching that is controlled from serial data.
• Serial data I/O supports CCB format communication
with the system controller.
• Direct display of display data without the use of a
decoder provides high generality.
• Independent VLCD for the LCD driver block (VLCD can
be set to in the range VDD-0.5 to 6.0 volts.)
• Provision of an on-chip voltage-detection type reset
circuit prevents incorrect displays.
• RC oscillator circuit.

Segment outputs for displaying the display data transferred by serial data input.
The S1/P1 to S4/P4 pins can be used as general-purpose output ports under serial
data control.
Common driver outputs
The frame frequency fo is given by : fo = (fOSC/384)Hz.
Key scan outputs
Although normal key scan timing lines require diodes to be inserted in the timing lines
to prevent shorts, since these outputs are unbalanced CMOS transistor outputs, these
outputs will not be damaged by shorting when these outputs are used to form a key
matrix. The KS1/S24 and KS2/S25 pins can be used as segment outputs when so
specified by the control data.
Key scan inputs
These pins have built-in pull-down resistors.
Oscillator connection
44 An oscillator circuit is formed by connecting an external resistor and capacitor at this
pin.
