• General-purpose embedded computing tasks

Procurement Notes

Verify the specific suffix 'CU' corresponds to the TFBGA-100 package and industrial temperature grade when sourcing. Confirm that the supplier provides official datasheets matching the ATSAM4S2CA-CU designation. Ensure compliance with RoHS standards as indicated by manufacturer specifications. Cross-reference assembly location notices for any recent manufacturing changes.

Selection Notes

Select this component when a balance of moderate memory capacity and high-speed processing is required in a compact surface-mount package. Consider the TFBGA-100 form factor for space-constrained designs. Evaluate peripheral requirements against the available USB, ADC, and timer resources. Compare against other SAM4S variants if different memory sizes or pin counts are necessary.

Part Context

This part belongs to the SAM4S family of microcontrollers based on the ARM Cortex-M4 architecture. It shares architectural similarities with other members like the ATSAM4S2CA-AU but differs in packaging and potentially environmental ratings. The series is designed for applications demanding real-time control and multimedia processing capabilities within the 32-bit MCU segment.

Replacement Considerations

ATSAM4S2CA-AU offers similar specifications but uses an LQFP-100 package instead of TFBGA-100. Designers must account for footprint differences during substitution. Other SAM4S variants may provide increased memory but require software adaptation due to peripheral variations.
