S1 to S64
1 to 64
Segment driver outputs.
S65/COM9

S65/COM9 can be used as common driver output pin under the
-
O
OPEN
"set display technique" instruction.
COM1 to COM8
73 to 66
Common driver outputs.

KS1/P1
KS2/P2
KS3 to KS6

76 to 79
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
KS7/P3
85
outputs will not be damaged by shorting when these outputs are
used to form a key matrix.
-
O
OPEN
KS1/P1, KS2/P2, and KS7/P3 can be used as general-purpose
output ports under the "set key scan output port/general-purpose
output port state" instruction.
KI1 to KI5
80 to 84
Key scan inputs.
These pins have built-in pull-down resistors.

OSC
95
Oscillator connections. An oscillator circuit is formed by
connecting an external resistor and capacitor to this pin.
This pin can also be used as the external clock input pin with the
-

"set display technique" instruction.
CE

Serial data interface connections to the controller. Note that DO,

INH
96
Input that turns the display off, disables key scanning, and
forces the general-purpose output ports low.
? When INH is low (VSS):
? Display off
S1 to S64=”L” (VLCD4)
S65/COM9=”L” (VLCD4)
COM1 to COM8=”L” (VLCD4)
? General-purpose output ports P1 to P3=low (VSS)
? Key scanning disabled: KS1 to KS7=low (VSS)
? All the key data is reset to low.
L
I
VDD
? When INH is high (VDD):
? Display on
? The state of the pins as key scan output pins or
general-purpose output ports can be set with the
"set key scan output port/general-purpose output
port state" instruction.
? Key scanning is enabled.
However, serial data can be transferred when the INH pin is low.
TEST
94
This pin must be connected to ground.
-
I
-
VLCD0
88
LCD drive 4/4 bias voltage (high level) supply pin. The level on this
pin can be changed by the display contrast adjustment circuit.
However, (VLCD0 - VLCD4) must be greater than or equal to 4.5V.
-
O
OPEN
Also, external power must not be applied to this pin since the pin
circuit includes the display contrast adjustment circuit.
VLCD1
89
LCD drive 3/4 bias voltage (middle level) supply pin. This pin can
be used to supply the 3/4 (VLCD - VLCD4) voltage level externally.
-
I
OPEN
VLCD2
90
LCD drive 2/4 bias voltage (middle level) supply pin. This pin can
be used to supply the 2/4 (VLCD0 - VLCD4) voltage level
-
I
OPEN
externally.
