Procurement Notes

Verify the specific suffix 'MFT' against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with design-in tools and check for any recent product change notices affecting this variant.

Selection Notes

Select this component when both cryptographic security and low power consumption are required. Compare pin counts and memory sizes against other SAM L11 variants to ensure optimal fit for the target application's interface and storage needs.

Part Context

This part belongs to the SAM L11 family, designed for secure, low-power applications. It shares the Cortex-M23 core with other members but differs in memory size and package options. The D16 designation typically indicates the 64 KB flash configuration within this series.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified substitutes. Consider ATSAML11D16A-MUT or ATSAML11D16A-MU if package differences are acceptable.
