Microcontrollers Procurement Notes

Verify the specific ordering suffix against the official S32K1xx_Orderable_Part_Number_List.xlsx attachment to ensure correct package and temperature grade. Confirm that the selected variant matches the required pin count and peripheral availability for your design. Check for any recent product change notifications regarding labeling or manufacturing sites.

Microcontrollers Selection Notes

Select this part when high-performance processing at 112 MHz is required alongside robust automotive safety features. Ensure the application utilizes the full 2 MB flash capacity, as smaller variants exist. Verify that the 100-pin LQFP package provides sufficient I/O lines for the interface requirements. Consider thermal dissipation capabilities if operating continuously at maximum frequency.

Microcontrollers Part Context

This component belongs to the S32K14x family, which offers scalable memory and peripheral options. It shares architectural similarities with the S32K144 and S32K146 but provides larger memory resources. The series is designed for general-purpose automotive applications requiring AEC-Q100 qualification and extensive connectivity options.

Microcontrollers Replacement Considerations

Direct substitutes include other S32K148 variants with different packages or temperature grades, such as those in MAPBGA or QFN formats. Cross-referencing the feature comparison table is essential to ensure peripheral compatibility before substitution.
