Pin Functional Description (cont)
Signal
Number
of Pins
I/O
Device
Interfaced with Function
Vci
2
I
Power supply
Inputs a reference voltage and supplies power to the
booster; generates the liquid crystal display drive voltage
from the operating voltage.
V5OUT2
1
O
V
pin/ Booster
capacitance
Voltage input to the Vci pin is boosted twice and output.
When the voltage is boosted three times, the same
capacitance as that of C1–C2 should be connected here.
V5OUT3
1
O
V
EE
pin
Voltage input to the Vci pin is boosted three times and
output.
C1/C2
2
—
Booster
capacitance
External capacitance should be connected here when
using the booster.
RESET*
1
I
—
Reset pin. Initializes the LSI when low.
EXM
1
I
MPU
External alternating signal used for annunciator display
during standby mode. If annunciator display is not used,
EXM must be fixed to V
CC
or GND.
Selects the SEG output pin arrangement: when SFT =
GND, SEG1 is connected to the far left of the LCD panel
and when SFT = V
CC
, SEG60 is connected to the far left of
the LCD panel
SFT
1
I
V
CC
or GND
OPOFF
1
I
V
CC
or GND
Turns the internal operational amplifier off when OPOFF =
V
, and turns it on when OPOFF = GND. If the amplifier is
turned off (OPOFF = V
CC
), V1 to V5 must be supplied to the
V1OUT to V5OUT pins.
TEST
1
I
GND
Test pin. Must be grounded.
