2.3.9 XTAL2

2.3.10 AVCC

2.3.11 AREF

Reset input. A low level on this pin for longer than the minimum pulse length will generate a

reset, even if the clock is not running. The minimum pulse length is given in ”System and Reset

Characteristics” on page 332. Shorter pulses are not guaranteed to generate a reset.

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 A and the Analog-to-digital Converter. It should be exter-

nally connected 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 Analog-to-digital Converter.

3. Resources

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

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

4. 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.
