Procurement Notes
Verify the specific suffix 'MNR' corresponds to the tape-and-reel packaging format and the 64-QFN footprint. Confirm assembly site and moisture sensitivity level requirements against current datasheet revisions before finalizing procurement orders.
Selection Notes
Select this component when a balance of processing power and peripheral density is required in a compact surface-mount package. Ensure the design accommodates the 64-pin QFN thermal pad requirements and validates compatibility with the 1.62V to 3.6V operating voltage range.
Part Context
This part belongs to the SAM4S family, which targets cost-sensitive applications demanding ARM Cortex-M4 performance. It shares architectural similarities with other SAM4S variants but differs in memory size and package options, offering a mid-range solution within the broader microcontroller portfolio.
Replacement Considerations
ATSAM4S4BB-AN provides identical electrical specifications in a 64-LQFP package. ATSAM4S4CB-CN offers similar performance in a TFBGA-100 package with extended temperature ratings.
