[1] Current numbers are for reduced configuration and may vary based on user configuration and silicon process variation.

[2] See the configurations in Table 23.

[3] RUN IDD @ V15 includes Flash memory read current from the V11 voltage rail.

[4] IO current is not included. The actual current requirements for IOs will depend on the I/O configuration in the application.

[5] RUN IDD @ VDD_HV_A includes Flash memory read current from the V25 voltage rail.

[6] For S32K389, the current from a V15 supply will flow through the external NMOS for the V11 regulation stage, and into the V11 pins of the device.

[7] “typ” is indicative of the average current numbers at the nominal internally regulated V11 supply voltage, VDD_HV_A = 5.0V, VDD_HV_B = 5.0V, V15 = 1.5V, for

the typical silicon process.

[8] “max” is indicative of the maximum current numbers at the maximum internally regulated V11 supply voltage (1.16 V), VDD_HV_A = 5.5V, VDD_HV_B = 5.5V,

V15 = 1.65V, for the fast silicon process.
