Procurement Notes

Verify the complete part number including the suffix KPH, which indicates specific tape and reel packaging configuration. Confirm that the required operating temperature range (-40°C to +85°C) aligns with your system design specifications. Ensure compatibility with the 1.62V to 3.63V supply voltage domain. Cross-reference the 24-VQFN package dimensions against your PCB layout constraints to ensure proper fitment and thermal performance.

Selection Notes

Select this component when both high security and low power are critical. The Cortex-M23 core provides efficient code execution compared to older architectures. Consider the 64KB Flash limit for complex firmware requirements. Evaluate if the integrated crypto engine meets your specific algorithm needs without external components. Compare against the ATSAML11E series if different peripheral counts or package options are preferred.

Part Context

This MCU belongs to the SAM L11 family, which focuses on combining ARM TrustZone security with ultra-low-power performance. It shares architectural similarities with other SAM L11 variants but offers specific memory sizes and peripheral configurations. The device is part of Microchip's strategy to provide secure, energy-efficient solutions for connected devices in demanding environments.

Replacement Considerations

ATSAML11D16A-MUT: Identical electrical and functional specifications; differs only in bulk packaging rather than tape and reel format.
