1. S32K148 will operate from 2.7 V when executing from internal FIRC. When the PLL is engaged S32K148 is guaranteed to
operate from 2.97 V. All other S32K family devices operate from 2.7 V in all modes.

4. The value given is measured at high drive strength mode. For value at low drive strength mode see the Ioh_Standard
value given above.
5. The value given is measured at high drive strength mode. For value at low drive strength mode see the Iol_Standard value
given above.
6. Several I/O have both high drive and normal drive capability selected by the associated Portx_PCRn[DSE] control bit. All
other GPIOs are normal drive only. For details refer to S32K144_IO_Signal_Description_Input_Multiplexing.xlsx attached
with the Reference Manual.
7. When using ENET and SAI on S32K148, the overall device limits associated with high drive pin configurations must be
respected i.e. On 144-pin LQFP the general purpose pins: PTA10, PTD0, and PTE4 must be set to low drive.
