Microcontrollers Procurement Notes

Verify the specific ordering suffix against the official S32K1xx Orderable Part Number List to ensure correct package, temperature grade, and feature set. Confirm that the requested variant matches the required pin count and peripheral configuration for your design.

Microcontrollers Selection Notes

Select this part when ASIL-B capability and cryptographic security are required alongside standard connectivity. Ensure the system design accommodates the power modes and thermal characteristics defined for the V-Grade or M-Grade variants depending on the application environment.

Microcontrollers Part Context

This component belongs to the S32K14x family, designed for general-purpose automotive applications. It shares architectural similarities with other members like the S32K144 and S32K148 but offers specific memory sizes and peripheral counts tailored for mid-range performance requirements.

Microcontrollers Replacement Considerations

Check the S32K1xx_Orderable_Part_Number_List.xlsx for direct substitutes. Pin-to-pin compatibility exists within the same package type across the S32K14x family, but verify memory and peripheral differences before swapping.
