[1]
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,
real-time clock, and watchdog timer.
[3]
The IDD(tpd) specication is measured using an external clock with the following functions disabled: comparators, real-time clock,
brownout detect, and watchdog timer.
[4]
VOL/VOH may exceed the related specication.
[5]
This specication can be applied to pins which have analog comparator input functions when the pin is not being used for those analog
functions. When the pin is being used as an analog input pin, the maximum voltage on the pin must be limited to 4.0 V with respect to
VSS.
[6]
Pin capacitance is characterized but not tested.
[7]
Measured with port in quasi-bidirectional mode.
[8]
Measured with port in high-impedance mode.
[9]
Port pins source a transition current when used in quasi-bidirectional mode and externally driven from logic 1 to logic 0. This current is
highest when VI is approximately 2 V.
