Microcontrollers Procurement Notes

Verify the specific ordering suffix against the official S32K1xx Orderable Part Number List to ensure availability. Confirm that the package type and temperature grade match the design requirements. Check for any regional manufacturing qualifications if applicable. Ensure compatibility with existing development tools and software development kits before finalizing procurement decisions.

Microcontrollers Selection Notes

Select this part when a balance of processing performance and security is required for body or chassis applications. The 80 MHz speed and 256 KB memory size suit moderate complexity tasks. Consider the available packages and peripheral count relative to the board layout constraints. Evaluate the need for CAN FD and Ethernet support compared to lower-end variants in the S32K1xx series.

Microcontrollers Part Context

This component belongs to the S32K14x series within the broader S32K1xx family. It shares architectural similarities with other devices like the S32K142HAT0MLFT but differs in memory configuration and feature set. The S32K14x series targets applications requiring higher performance than the K11x series while maintaining functional safety standards.

Microcontrollers Replacement Considerations

Direct substitutes include other S32K142 variants such as S32K142HAT0MLFT or S32K142HAT0VLHT, provided they meet the specific package and temperature requirements. Verify pin-to-pin compatibility and memory sizes when considering cross-references within the S32K1xx family.
