[1] The supply current is obtained through the measurements of the current during the corresponding operating mode.

[2] The duration is defined by the application (how much time will the device spend in the according operating mode).

[3] The ratio of duration is obtained by dividing the duration of the corresponding operating mode by the total duration of the application.

[4] The current according to ratio is obtained by multiplying the supply current and the ratio of duration related to the proper operating mode.

[5] The average current is calculated by the addition of each device operating mode’s current according to ratio.

7 I/O parameters

7.1 GPIO DC electrical specifications, 3.3V Range (2.97V - 3.63V)

The leakage current on the GPIO pins is specified as a function of the pad type (Standard, Standard Plus, Medium, Fast, or GPI)

and the number of Analog functions (CMP and ADC channels) multiplexed per pin.

For S32K388, see the ILKG column in the Pinout section of the IOMUX file attached to the Reference Manual.

For other devices, the "Analog Function Count" is defined from the number of CMP and ADC channels multiplexed to a given

pin. This information can be obtained from the "Direct Signals" column in the IOMUX files attached to the Reference Manual. The

"Analog Function Count" is shown in the Condition column of the following table.
