Cautions
Remark
The 78K0/LF2 contains a booster circuit ( 3 only) to generate a supply voltage to drive the LCD. The internal LCD
The LCD reference voltage (V
The 78K0/LF2 requires an external capacitor (0.47 to 1 F: recommended) when the internal voltage boosting
Use a capacitor with as little leakage as possible.
In addition, make C1 a nonpolar capacitor.

When using the LCD function, do not leave the V
Figure 17-30 for connection.
Since the LCD drive voltage is separate from the main power supply, a constant voltage
can be supplied regardless of V
