12-bit A/D converter

AN000 to AN007,

AN100 to AN111

Input

Input pins for the analog signals to be processed by the A/D

converter

ADTRG0#, ADTRG1#

Input

Input pins for the external trigger signals that start the A/D

conversion

ANEX0

Output

Extended analog output pin

ANEX1

Input

Extended analog input pin

Capacitive touch sensing

unit (CTSU)

TS0 to TS16

I/O

Electrostatic capacitance measurement pins (touch pins).

TSCAP

—

Connect to the VSS via a decoupling capacitor (10 nF) for

stabilizing the internal voltage. The capacitor should be placed

close to the pin.

Analog power supply

AVCC0*1

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*1

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*1

Input

Analog voltage supply and reference voltage supply pin for the

12-bit A/D converter (unit 1). 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*1

Input

Analog voltage supply and reference voltage supply pin for the

12-bit A/D converter (unit 1). 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.
