Note: 1.

“Max” means the highest

value where the pin is guaranteed to be read as low.

2.“Min” means the lowest value where the pin is guaranteed to be read as high.

3.Although each I/O port can sink more than the test conditions (20 mA at VCC = 5V, 10 mA at VCC = 3V) under steady state conditions (non-transient), the following must be observed:

1] The sum of all IOL, for all ports, should not exceed 100 mA.

If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test conditions.

4.Although each I/O port can source more than the test conditions (3 mA at VCC = 5V, 1.5 mA at VCC = 3V) under steady state conditions (non-transient), the following must be observed:

1] The sum of all IOH, for all ports, should not exceed 100 mA.

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.

5.Minimum VCC for power-down is 1.5V (only with BOD disabled).

Typical Characteristics – PRELIMINARY DATA

The following charts show typical behavior. These data are characterized but not tested. All current consumption measurements are performed with all I/O pins configured as inputs and with internal pull-ups enabled.

The 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.

The current drawn from capacitive loaded pins may be estimated (for one pin) as CL•VCC•f where CL = load capacitance, VCC = operating voltage and f = average switching frequency of I/O pin.

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.
