3.3.14 XTAL2

3.3.15 AVCC

3.3.16 AREF

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

through a low-pass filter.

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

4. Resources

A comprehensive set of development tools, application notes and datasheets are available for

download on http://www.atmel.com/avr.

5. Data Retention

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.
