Atmel ATmega88PA

8161AS–AVR–11/08

ATmega88PA

The various special features of Port D are elaborated in ”Alternate Functions of Port D” on page

80.

1.1.7 AVCC AVCC is the supply voltage pin for the A/D Converter, PC3:0, and ADC7:6. It should be externally

connected to VCC, even if the ADC is not used. If the ADC is used, it should be connected to VCC

through a low-pass filter. Note that PC6..4 use digital supply voltage, VCC.

1.1.8 AREF

AREF is the analog reference pin for the A/D Converter.

1.1.9 ADC7:6 (TQFP and QFN/MLF Package Only)

In the TQFP and QFN/MLF package, ADC7:6 serve as analog inputs to the A/D converter.

These pins are powered from the analog supply and serve as 10-bit ADC channels.
