Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type, temperature grade, and security features. Ensure compatibility with existing design-in requirements before procurement. Cross-reference the part number with the latest datasheet revision to validate all technical specifications.

Microcontrollers Selection Notes

Select this component for designs requiring ASIL B functional safety certification combined with robust hardware security. The 120 MHz performance level is suitable for body control and gateway applications. Verify that the HDQFP100 package meets the board space constraints and that the 1 MB flash capacity aligns with software storage needs.

Microcontrollers Part Context

This MCU belongs to the S32K3xx family, which extends the S32K portfolio with higher-performance Cortex-M7 cores. It shares pinouts and peripherals with other members of the series, facilitating migration between devices with varying memory sizes or core configurations within the same ecosystem.

Microcontrollers Replacement Considerations

S32K310 offers similar functionality with reduced memory capacity. S32K312 provides increased flash storage while maintaining the same core configuration.
