Segment outputs: Used to output the display data that is transmitted over the
serial data input. Pins S1/P1 to S4/P4 can be used as general-purpose outputs
according to control data specification.
Common driver outputs. The frame frequency f
O
is (f
OSC
/512) Hz.
Key scan outputs. When a key matrix is formed, normally a diode will be
attached to the key scan timing line to prevent shorts. However, since the
output transistor impedance is an unbalanced CMOS output, it will not be
damaged if shorted. Pins KS1/S44 and KS2/S45 can be used as segment
outputs according to control data specification.
Key scan inputs: Pins with a built-in pull-down resistor.
Oscillator connection: Oscillator circuit can be formed by connecting the pin to
a resistor and a capacitor.
CE: Chip enable
CL: Synchronization clock
DI: Transfer data
DO: Output data
Serial data interface: Connected
to the controller. Since DO is an
open-drain output, it requires a
pull-up resistor.
Reset input that re-initializes the LSI internal states. During a reset, the display
segments are turned off forcibly regardless of the internal display data. All
internal key data is reset to low and the key scan operation is disabled.
However, serial data can be input during a reset.
Power supply connection. A supply voltage of between 4.5 and 6.0 V must be
provided.
Power supply ground connection. Must be connected to GND.
