Typical ratings are not guaranteed. The values listed are at room temperature, 3 V.
[2]
The IDD(oper),IDD(idle), and IDD(PD) specications are measured using an external clock with the following functions disabled: comparators,
brownout detect, and Watchdog timer.
[3]
See Table 7 “Limiting values[1]” on page 35 for steady state (non-transient) limits on IOL or IOH. If IOL/IOH exceeds the test condition,
VOL/VOH may exceed the related specication.
[4]
Pin capacitance is characterized but not tested.
[5]
Measured with port in quasi-bidirectional mode.
[6]
Measured with port in high-impedance mode.
[7]
Ports in quasi-bidirectional mode with weak pull-up (applies to all port pins with pull-ups). Does not apply to open-drain pins.
[8]
Port pins source a transition current when used in quasi-bidirectional mode and externally driven from ‘1’ to ‘0’. This current is highest
when VIN is approximately 2 V.
