DB0/KIN0–

I/O or
I
MPU or key
matrix
Serves as a bidirectional data bus for a parallel bus
interface.
For a 4-bit bus, data transfer uses KIN7/DB7-
KIN4/DB4; leave KIN3/DB3-KIN0/DB0 disconnected.
Samples key state from key matrix synchronously
with strobe signals for a serial interface.
PORT0–
PORT2
3
O
General output
General output ports. These ports cannot drive
current such as for LEDs or backlighting control.
Boost the current using an external transistor.
COM1/80–
COM80/1
80
O
LCD
Common output signals for character/graphics
display: COM1 to COM8 for the first line, COM9 to
COM16 for the second line, COM17 to COM24 for
the third line, COM25 to COM32 for the fourth line,
and COM73 to COM80 for the 10th line. All the
unused pins output unselected waveforms. In the
sleep mode (SLP = 1) or standby mode (STB = 1), all
pins output GND level.
The CMS bit can change the shift direction of the
common signal. For example, if CMS = 0, COM1/80
is COM1. If CMS = 1, COM1/80 is COM80.
Note that the start position of the common output (the
first line) is shifted by CN1–CN0 bits.
SEG1/112–
SEG112/1
112
O
LCD
Segment output signals for character or graphics
display. In the sleep mode (SLP = 1) or standby
mode (STB = 1), all pins output GND level.
The SGS bit can change the shift direction of the
segment signal. For example, if SGS = 0, SEG1/112
is SEG1. If SGS = 1, SEG1/112 is SEG112.
V1OUT–
V5OUT

I or O
Open or
external
bleeder-resistor
Used for output from the internal operational
amplifiers when they are used (OPOFF = GND);
attach a capacitor to stabilize the output. When the
amplifiers are not used (OPOFF = V
), V1 to V5
voltages can be supplied to these pins externally.

For R-C oscillation using an external resistor, connect
an external resistor. For external clock supply, input

Power supply
Inputs a reference voltage and supplies power to the
booster; generates the liquid crystal display drive
voltage from the operating voltage. The boosting
output voltage must not be larger than the absolute
maximum ratings.
Must be left disconnected when the booster is not
used.
