Procurement Notes

Verify the specific suffix 'AN' against official Microchip documentation to confirm pinout compatibility and package dimensions. Ensure that the selected variant meets the required environmental specifications for your target application. Cross-reference the datasheet revision history to validate peripheral availability and electrical characteristics prior to finalizing procurement plans.

Selection Notes

Select this component when design requirements include integrated Ethernet and USB connectivity within a single MCU. Consider the 120 MHz processing speed for applications demanding real-time data handling. Evaluate the 144-pin package constraints against available PCB space. Confirm that the 128 kB RAM suffices for complex operating system or large buffer requirements.

Part Context

This part belongs to the SAM4E family, designed for high-performance embedded applications. It bridges the gap between low-cost MCUs and external memory solutions by integrating substantial storage and advanced peripherals directly on-chip. The architecture emphasizes code protection and security features suitable for sensitive industrial and commercial deployments.

Replacement Considerations

Consult official substitution lists for variants with different memory sizes or package types within the SAM4E family. Verify pin-to-pin compatibility before replacing existing inventory. Note that changes in suffix letters may indicate differences in temperature range or packaging rather than functional equivalence.
