Procurement Notes
Verify the specific suffix 'ANT' indicates tape and reel packaging when sourcing components. Confirm the manufacturer part number matches exactly to ensure correct pinout and electrical specifications. Check current datasheet revisions for any errata or design updates relevant to the SAM E/S/V70 family before finalizing procurement orders.
Selection Notes
Select this component for applications requiring high-speed processing combined with robust connectivity features. The 100-pin LQFP package offers a balance between pin count and board space. Ensure the design accommodates the required supply voltage range and thermal dissipation for the specified operating temperature range.
Part Context
This microcontroller belongs to the SAM S70 family, designed for high-performance embedded applications. It shares architectural similarities with the SAM E70 and V71 series but may differ in specific peripheral configurations or package availability. The device is positioned for complex control tasks requiring significant computational power and data handling capabilities.
Replacement Considerations
Direct substitutes within the same package and pinout include other variants from the SAM S70 family with equivalent memory sizes, such as ATSAMS70N19A-AN if reduced memory is acceptable. Cross-family replacements like the SAM E70 series require verification of peripheral compatibility and software migration efforts.
