I/O
DESCRIPTION
AVCC
64
Positive terminal that supplies SVS, brownout, oscillator, comparator_A, port 1, and LCD resistive
divider circuitry; must not power up prior to DVCC.
AVSS
62
Negative terminal that supplies SVS, brownout, oscillator, comparator_A. Needs to be externally
connected to DVSS.
DVCC
1
Digital supply voltage, positive terminal. Supplies all parts, except those which are supplied via AVCC.
DVSS
63
Digital supply voltage, negative terminal. Supplies all digital parts, except those which are supplied via
AVCC/AVSS.
NC
7, 10, 11
Not internally connected. Connection to VSS recommended.
