Procurement Notes

Verify the specific suffix AN indicates the 100-LQFP packaging configuration before ordering. Confirm that the required pin count aligns with the 75 available I/Os on this package variant. Ensure design compatibility with the specified voltage range and thermal characteristics for the target application environment.

Selection Notes

Select this component when high computational throughput is required alongside robust connectivity features. The combination of large memory capacity and extensive peripheral support makes it suitable for complex applications. Consider the LQFP package constraints regarding board space and thermal dissipation requirements during the initial hardware design phase.

Part Context

This part belongs to the SAM E70 family, designed for high-performance embedded applications. It shares architectural similarities with other members like the ATSAMS70N20A but differs in specific feature sets and package options. The E70 series emphasizes connectivity and processing power for demanding industrial and commercial uses.

Replacement Considerations

ATSAME70N20A-CN offers identical electrical specifications but utilizes a TFBGA package instead of LQFP.
