Notes 1. Value of current at which the device operation is guaranteed even if the current flows from the VDD pin to an
output pin.
2. Do not exceed the total current value.
3. This is the output current value under conditions where the duty factor ≤ 70%.
The output current value when the duty factor > 70% can be calculated with the following expression (when
changing the duty factor to n%).
• Total output current of pins = (I
OH × 0.7)/(n × 0.01)
<Example> Where n = 80 % and I
OH = - 10.0 mA
Total output current of pins = (- 10.0 × 0.7)/(80 × 0.01) ≅ - 8.7 mA
• Total output current of pins = (I
OL × 0.7)/(n × 0.01)
<Example> Where n = 80 % and I
OL = 10.0 mA
Total output current of pins = (10.0 × 0.7)/(80 × 0.01) ≅ 8.7 mA
However, the current that is allowed to flow into one pin does not vary depending on the duty factor. A
current higher than the absolute maximum rating must not flow into one pin.
4. Value of current at which the device operation is guaranteed even if the current flows from an output pin to
the V
SS pin.
Caution P00, P01, P06, and P07 do not output high level in N-ch open-drain mode.
Remark Unless specified otherwise, the characteristics of alternate-function pins are the same as those of the port.
