Pin Functions
Segment outputs for displaying the display data transferred by serial
data input.
The S1/P1 to S8/P8 pins can be used as general-purpose output ports
under serial data control.
Common driver outputs
The frame frequency fo is given by : fo = (f
OSC
/384)Hz.
The COM4/S74 pin can be used as a segment output in 1/3 duty.
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/S75 and
KS2/S76 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
An oscillator circuit is formed by connecting an external resistor and
capacitor at this pin.
Serial data interface connections to the controller. Note that DO, being
an open-drain output, requires a pull-up resistor.
CE :Chip enable
CL :Synchronization clock
DI :Transfer data
DO :Output data
L
Reset signal input
RES = low.....Display off
Key scan disabled
All key data is reset to low
RES = high....Display on
Key scan enabled
However, serial data can be transferred when RES is low.
Used for applying the LCD drive 2/3 bias voltage externally. Must be
connected to V
LCD

Used for applying the LCD drive 1/3 bias voltage externally. Must be
connected to V
LCD
1 when a 1/2 bias drive scheme is used.
Logic block power supply connection. Provide a voltage of between 4.5
and 6.0V.
LCD driver block power supply connection. Provide a voltage of
between V
