Power

supply

This is a capacitance pin for power supply stabilization.

Connect an external ceramic capacitor rated at about 0.1 µF. This

capacitor is not, however, required for the M90F523 (flash

product).

This is a pin for the reference power supply for the LCD controller/

driver.

This is a power supply (5.0 V) input pin to the digital circuit.

Power This provides the GND level (0.0 V) input pin for the digital circuit.

supply

H

This is a power supply for the analog circuit.

Make sure to turn on/turn off this power supply with a voltage

exceeding AVCC applied to VCC.

J

This is a reference voltage input to the analog circuit.

Make sure to turn on/turn off this power supply with a voltage

exceeding AVRH applied to AVCC.

H

This is a reference voltage input to the analog circuit.

H

This is a GND level of the analog circuit.

H

This is the Vref input pin for the D/A converter.

The voltage to be applied must not exceed VCC.

H

This is the GND level pin for the D/A converter.

The potential must be the same as VSS.
