AVCC
AREF
Input to the inverting Oscillator amplifier and input to the internal clock operating circuit.
Output from the inverting Oscillator amplifier.
AVCC is the supply voltage pin for Port F and the A/D Converter. It should be externally con-
nected to V
through a low-pass filter.
This is the analog reference pin for the A/D Converter.
A comprehensive set of development tools, application notes and datasheets are available for
download on http://www.atmel.com/avr.
Note:
Reliability Qualification results show that the projected data retention failure rate is much less
than 1 PPM over 20 years at 85°C or 100 years at 25°C.
