Notes 1. Value of current at which the device operation is guaranteed even if the current flows from V
pin.
2. Value of current at which the device operation is guaranteed even if the current flows from an output pin to
GND.
3. Specification under conditions where the duty factor is 70% (time for which current is output is 0.7 × t and
time for which current is not output is 0.3 × t, where t is a specific time). The total output current of the pins
at a duty factor of other than 70% can be calculated by the following expression.
• Where the duty factor of I
<Example> Where the duty factor is 50%, I
Total output current of pins = (20.0 × 0.7)/(50 × 0.01) = 28.0 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.
Remark Unless specified otherwise, the characteristics of alternate-function pins are the same as those of port pins.
