AVCC
AREF
ADC7..6 (TQFP and
QFN/MLF Package
Only)
AVCC is the supply voltage pin for the A/D Converter, Port C (3..0), and ADC (7..6). It should be
externally connected to VCC, even if the ADC is not used. If the ADC is used, it should be con-
nected to VCC through a low-pass filter. Note that Port C (5..4) use digital supply voltage, VCC.
AREF is the analog reference pin for the A/D Converter.
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.
