ATmega16A
2.2.7
RESET
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
Table 27-2 on page
296.
Shorter pulses are not guaranteed to generate a reset.
2.2.8
XTAL1
Input to the inverting Oscillator amplifier and input to the internal clock operating circuit.
2.2.9
XTAL2
Output from the inverting Oscillator amplifier.
2.2.10
AVCC
AVCC is the supply voltage pin for Port A and the A/D Converter. It should be externally con-
nected to V
CC
, even if the ADC is not used. If the ADC is used, it should be connected to V
CC
through a low-pass filter.
2.2.11
AREF
AREF is the analog reference pin for the A/D Converter.

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.
