Procurement Notes

Verify the specific suffix CN indicates compliance with RoHS3 standards and restricted substance requirements. Confirm the 100-TFBGA package dimensions match your PCB footprint design. Ensure ESD handling procedures are followed due to the surface-mount technology. Cross-reference the datasheet revision to confirm peripheral availability and errata status before finalizing procurement specifications.

Selection Notes

Select this component when a balance of moderate flash capacity and high-speed USB connectivity is required in a compact form factor. Compare against other SAM4S variants if larger memory sizes or different pin counts are needed. Consider the TFBGA package constraints regarding thermal dissipation and soldering reflow profiles during the design phase.

Part Context

This part belongs to the Microchip SAM4S family of Flash microcontrollers based on the ARM Cortex-M4 architecture. The series offers scalable memory configurations and peripheral sets designed for cost-sensitive embedded applications. The ATSAM4S2CB-CN represents a specific configuration optimized for industrial environments with extended temperature ratings and standard packaging.

Replacement Considerations

Direct substitutes within the same package and pinout include other SAM4S variants with identical memory maps, such as ATSAM4S2CA-CN. Verify functional equivalence by comparing peripheral lists and electrical characteristics against the original datasheet specifications.
