5.1 Absolute maximum ratings

When the MCU is in an unpowered state, current injected through the chip pins may bias internal chip structures

(for example, ESD diodes) and incorrectly power up these internal structures through inadvertent paths. The

presence of such residual voltage may influence different chip-internal blocks in an unpredictable manner and

may ultimately result in unpredictable chip behavior (for example, POR flag not set). Once in the illegal state,

powering up the chip further and then applying reset will clear the illegal state. Injection current specified for the

chip under the aspect of absolute maximum ratings represent the capability of the internal circuitry to withstand

such condition without causing physical damage. Functional operation of the chip under conditions - specified

as absolute maximum ratings - is not implied.

CAUTION

Functional operating conditions appear in the DC electrical characteristics. Absolute maximum ratings are stress

ratings only, and functional operation at the maximum values is not guaranteed. See footnotes in the following table

for specific conditions. Stress beyond the listed maximum values may affect device reliability or cause permanent

damage to the device. All the limits defined in the datasheet specification must be honored together and any

violation to any one or more will not guarantee desired operation. Unless otherwise specified, all maximum and

minimum values in the datasheet are across process, voltage, and temperature.

NOTE

The VDD_HV_B and V15 voltage supply domains are only present in certain devices and packages (S32K388, S32K358,

S32K348, S32K338, S32K328, S32K344, S32K324, S32K314, S32K342, S32K341, S32K322).

The VDD_DCDC supply voltage is only present in certain devices and packages (S32K358, S32K348, S32K338,

S32K328, S32K388).
