5.2 Voltage and current operating requirements

Device functionality is guaranteed down to the LVR assert level, however electrical performance of 12-bit ADC,

CMP with 8-bit DAC, IO electrical characteristics, and communication modules electrical characteristics will be

degraded when voltage drops below 2.97 V.

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).
