Device

I/O Interfaced with Function

— Power supply

— Oscillation

resistor clock

VCC: +2.7V to 5.5V, GND: 0V

When CR oscillation is performed, a resistor must be

connected externally. When the pin input is an external

clock, it must be input to OSC1.

O V5 pin/

Booster

capacitance

Input voltage to the booster, from which the liquid crystal

display drive voltage is generated.

Vci is reference voltage and power supply for the booster.

Vci = 1.0V to 5.0V ≤ VCC

Voltage input to the Vci pin is boosted twice and output

When the voltage is boosted three times, the same capacity

as that of C1–C2 should be connected.

O V5 pin

Voltage input to the Vci pin is boosted three times and

output.

— Booster

capacitance

External capacitance should be connected when using the

booster.

I

—

Test pin. Should be wired to ground.
