.
Drastic fluctuation by power supply voltage, input signal voltage noise, etc. causes malfunction and normal operation
can not be guaranteed. In any case, avoid intentionally changing the power supply voltage during operation.
TTL input pins: A

CMOS input pins: FR, M/S, RESX.

Input and output pins at high impedance: FR, D0 to D7.
This is the resistance when applying 0.1 V between the LCD drive output pins (SEG
0
to SEG
60
, COM
0
to COM
15
) and
the LCD drive power pins (V
1
, V
2
,V
3
, and V
4
pins). R
ON
is measured between the LCD drive power pins and the LCD
drive output pins whose electric potential is the same as that of the LCD drive power pins.
Current consumption when circuits, for example the oscillation circuit, the MPU interface, etc, are not operating.
Note 10 Current consumption by LCD panel and parasitic capacitance is not included.
Note 11 Current consumption when writing vertically-striped display data at t
CYC
=200 kHz. After the termination of command,
the current consumption value is I
DD1
.
Note 12 Reset time is from the point where RESX changed to the time when the reset operation is over and normal operation
becomes available.
Note 13 This is the inversion level of the input signal. Make the input signal go through the entire power supply voltage range.
If the input signal does not go the full range, current consumption will increase.
Note 14 When using a power supply voltage other than -5.0
±
0.5 V, the value is different. Check the power supply voltage.
