Procurement Notes
Verify the specific ordering suffix against official Microchip documentation to confirm package type, temperature grade, and tape-and-reel specifications. Ensure compatibility with required environmental conditions and interface configurations before procurement.
Selection Notes
Select this component when a balance of moderate memory capacity and extensive I/O connectivity is required alongside low-power operation. Consider the availability of USB and advanced timer features for applications needing precise timing or data transfer capabilities.
Part Context
This part belongs to the SAM4L family, designed for low-power applications using the Cortex-M4 architecture. It offers a trade-off between performance and energy efficiency, suitable for devices requiring extended battery life without sacrificing processing capability.
Replacement Considerations
Consult official substitution lists for compatible parts within the SAM4L series. Verify pinout and peripheral configuration matches before replacing.
