Procurement Notes
Verify the specific suffix 'ANT' corresponds to the LQFP-64 package variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly process specifications. Ensure the ordering part number matches the exact pin count and thermal characteristics required for your PCB layout design.
Selection Notes
Select this component when a balance of high computational density and rich peripheral integration is required in a compact footprint. It is suitable for applications needing simultaneous Ethernet and USB connectivity without external controllers. Consider alternative packages like BGA if higher pin counts or different thermal profiles are needed for the same core functionality.
Part Context
This unit belongs to the Microchip SAM S70 family, designed for high-performance embedded applications. It shares architectural similarities with the ATSAME70 series but may differ in specific peripheral configurations or certification levels. The device targets markets requiring robust real-time processing capabilities combined with advanced connectivity features.
Replacement Considerations
Direct substitutes include other variants within the SAM S70 family with compatible pinouts, such as ATSAMS70Q21B-ANT, provided functional differences in errata or peripheral availability are acceptable.
