1. Typical values at 25C.
2. “Min” means the lowest value where the pin is guaranteed to be read as high.
3. “Max” means the highest value where the pin is guaranteed to be read as low.
4. Although each I/O port can sink more than the test conditions (10mA at VCC = 5V, 5mA at VCC = 3V) under steady state
conditions (non-transient), the sum of all IOL (for all ports) should not exceed 60mA. If IOL exceeds the test conditions, VOL
may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test condition.
5. Although each I/O port can source more than the test conditions (10mA at VCC = 5V, 5mA at VCC = 3V) under steady
state conditions (non-transient), the sum of all IOH (for all ports) should not exceed 60mA. If IOH exceeds the test condition, VOH may exceed the related specification. Pins are not guaranteed to source current greater than the listed test
condition.
6. The RESET pin must tolerate high voltages when entering and operating in programming modes and, as a consequence,
has a weak drive strength as compared to regular I/O pins.
7. Values are with external clock. Power Reduction is enabled (PRR = 0xFF) and there is no I/O drive.
8. BOD Disabled.

It is possible to manually calibrate the internal oscillator to be more accurate than default factory calibration.
Note:

The oscillator frequency depends on temperature and voltage. Voltage and temperature characteristics can be

2. 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 indications 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.
This device has been characterised at temperatures of -40C, 25C, 85C and 125C.
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 operating 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 consumption 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:
I CP  V CC  C L  f SW
where VCC = operating voltage, CL = load capacitance and fSW = average switching frequency of I/O pin.
