Procurement Notes

Verify the specific suffix KPH indicates tray packaging and key-provisioned status against official datasheets. Confirm the operating temperature grade matches application requirements. Ensure compatibility with existing design tools and libraries before finalizing procurement decisions.

Selection Notes

Select this model when 64 KB Flash and 16 KB SRAM are required within a compact 24-pin form factor. Consider the 32 MHz speed and cryptographic features for applications demanding both performance and security. Compare against other SAM L11 variants if different memory sizes or package types are needed.

Part Context

This part belongs to the ATSAML11 series, designed for ultra-low power applications. It shares architectural similarities with other SAM L11 devices but differs in memory capacity and package configuration. The series targets cost-sensitive embedded systems requiring robust security features without significant power consumption overhead.

Replacement Considerations

ATSAML11D16A-MUT serves as a reel-packaged alternative with identical electrical specifications. ATSAML11D16A-MFTKPH offers the same specs in a 125°C temperature grade variant.
