Notes:
1. Typical values at +25°C.
2. “Max” means the highest value where the pin is guaranteed to be read as low.
3. “Min” means the lowest value where the pin is guaranteed to be read as high.
4. Not tested in production.
5. Although each I/O port can under non-transient, steady state conditions sink more than the test conditions, the sum of all I
OL
(for all ports) should not exceed 60 mA. If I
OL
exceeds the test condition, V
OL
may exceed the related specification. Pins are
not guaranteed to sink current greater than the listed test condition.
6. Although each I/O port can under non-transient, steady state conditions source more than the test conditions, the sum of all
I
OH
(for all ports) should not exceed 60 mA. If I
OH
exceeds the test condition, V
OH
may exceed the related specification. Pins
are not guaranteed to source current greater than the listed test condition.
7. Values are with external clock. Power Reduction is enabled (PRR = 0xFF) and there is no I/O drive.
8. BOD Disabled.

Accuracy of Calibrated Internal Oscillator
It is possible to manually calibrate the internal oscillator to be more accurate than default factory calibration. Note that the
oscillator frequency depends on temperature and voltage. Voltage and temperature characteristics can be found in
Figure
2-53 on page 32
,
Figure 2-54 on page 33
,
Figure 2-55 on page 33
, and in
Figure 2-56 on page 34
.
Notes:

Typical Characteristics
The data contained in this section is largely based on simulations and characterization of similar
devices in the same process and design methods. Thus, the data should be treated as indica-
tions of how the part will behave.
The following charts show typical behavior. These figures are not tested during manufacturing.
During characterisation devices are operated at frequencies higher than test limits but they are
not guaranteed to function properly at frequencies higher than the ordering code indicates.
All current consumption measurements are performed with all I/O pins configured as inputs and
with internal pull-ups enabled. Current consumption is a function of several factors such as oper-
ating voltage, operating frequency, loading of I/O pins, switching rate of I/O pins, code executed
and ambient temperature. The dominating factors are operating voltage and frequency.
A sine wave generator with rail-to-rail output is used as clock source but current consumption in
Power-Down mode is independent of clock selection. The difference between current consump-
tion in Power-Down mode with Watchdog Timer enabled and Power-Down mode with Watchdog
Timer disabled represents the differential current drawn by the Watchdog Timer.
The current drawn from pins with a capacitive load may be estimated (for one pin) as follows:
where V
CC
= operating voltage, C
L
= load capacitance and f
SW
= average switching frequency of
I/O pin.
