Analog power supply

AVCC0

Input

Analog voltage supply pin for the 12-bit A/D converter (unit 0).

Connect this pin to a branch from the VCC power supply.

Connect the pin to AVSS0 via a 0.1-µF multilayer ceramic

capacitor. The capacitor should be placed close to the pin.

AVSS0

Input

Analog ground pin for the 12-bit A/D converter (unit 0). Connect

this pin to a branch from the VSS ground power supply.

Connect the pin to AVCC0 via a 0.1-µF multilayer ceramic

capacitor. The capacitor should be placed close to the pin.

VREFH0

Input

Analog reference voltage supply pin for the 12-bit A/D converter

(unit 0). Connect this pin to VCC if the 12-bit A/D converter is

not to be used.

VREFL0

Input

Analog reference ground pin for the 12-bit A/D converter (unit

0). Connect this pin to VSS if the 12-bit A/D converter is not to

be used.

AVCC1

Input

Analog voltage supply and reference voltage supply pin for the

12-bit A/D converter (unit 1) and D/A converter. This pin also

supplies the analog voltage to the temperature sensor. Connect

this pin to a branch from the VCC power supply. Connect the

pin to AVSS1 via a 0.1-µF multilayer ceramic capacitor. The

capacitor should be placed close to the pin.

AVSS1

Input

Analog voltage supply and reference voltage supply pin for the

12-bit A/D converter (unit 1) and D/A converter. This pin also

supplies the analog ground voltage to the temperature sensor.

Connect this pin to a branch from the VSS ground power

supply. Connect the pin to AVCC1 via a 0.1-µF multilayer

ceramic capacitor. The capacitor should be placed close to the

pin.
