DESCRIPTION

NAME

NO.

I/O

DESCRIPTION

AVCC

Positive terminal that supplies SVS, brownout, oscillator, FLL+, comparator_A, port 1, and LCD

resistive divider circuitry; must not power up prior to DVCC.

AVSS

Negative terminal that supplies SVS, brownout, oscillator, FLL+, comparator_A. Needs to be externally

connected to DVSS.

DVCC

Digital supply voltage, positive terminal. Supplies all parts, except those which are supplied via AVCC.

DVSS

Digital supply voltage, negative terminal. Supplies all digital parts, except those which are supplied via

AVCC/AVSS.

7, 10, 11

Not internally connected. Connection to VSS recommended.
