• Integrated floating-point unit (FPU) within the ARM Cortex-M4F core for efficient mathematical processing.
• Comprehensive connectivity suite supporting Ethernet, USB Full-Speed, CAN bus, and various serial protocols.
• High-performance analog subsystem featuring multiple 12-bit ADC channels and 12-bit DAC outputs.

Applications

• Automotive body control modules and gateway systems
• Industrial motor drives and automation controllers
• Smart energy metering and utility infrastructure devices
• Advanced human-machine interface (HMI) panels

Procurement Notes

Verify the specific suffix 'CTUT' against official Microchip documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure that the AEC-Q100 Grade 1 qualification aligns with your target application's thermal requirements. Cross-reference the part number with the latest datasheet revision to confirm pinout compatibility and any silicon errata relevant to the SAM E54 family.

Selection Notes

Select this component when automotive reliability is required alongside high-speed connectivity options like Ethernet and USB. The 125°C junction temperature rating distinguishes it from commercial variants limited to 85°C. Consider the 192 KB RAM size relative to your application's stack and heap requirements. Verify that the 128-TQFP package fits your PCB footprint constraints compared to smaller BGA or TFBGA alternatives in the same series.

Part Context

This part belongs to the SAM E54 series, designed for cost-sensitive automotive and industrial applications requiring robust connectivity. It shares the core architecture with the SAM E53 but offers enhanced memory and peripheral configurations. The series targets applications needing deterministic real-time performance with low power consumption characteristics typical of ARM Cortex-M4 processors.

Replacement Considerations

Direct substitutes include other parts within the ATSAME54 family with matching memory sizes and packages, such as ATSAME54P19A-AUT-EFP. Verify that alternative candidates maintain the same AEC-Q100 qualification and 125°C operating temperature range to ensure functional equivalence in automotive designs.
