Procurement Notes

Verify the specific suffix 'AU' corresponds to the TQFP-100 package and commercial temperature range during sourcing. Confirm RoHS compliance status through official Microchip documentation. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when both Ethernet and USB connectivity are required on a single MCU. The 120 MHz Cortex-M4F core offers sufficient processing power for complex control loops. Compare against ATSAME53J variants if fewer I/O pins are acceptable for cost reduction. Consider the ATSAME53N20A variant if larger memory capacity is needed.

Part Context

This part belongs to the ATSAME53 family, designed for high-performance embedded applications requiring robust connectivity. It complements the SAM D and SAM L series by offering higher processing speeds and advanced peripherals like Ethernet. The family targets markets demanding reliable real-time control with networked capabilities.

Replacement Considerations

ATSAME53N19A-AUT-EFP serves as a reel-based alternative to the tray-packaged version.
