Procurement Notes
Verify the specific suffix 'ANR' indicates tape-and-reel packaging when ordering. Confirm the assembly site and RoHS compliance status via the latest datasheet or product change notification. Ensure compatibility with existing PCB footprints for the 100-TFBGA package before finalizing procurement plans.
Selection Notes
Select this model for designs requiring a balance of processing power and peripheral integration within a compact footprint. Compare against other SAM4S variants based on required Flash size and I/O count. Consider the TFBGA package constraints regarding thermal dissipation and soldering requirements during the design phase.
Part Context
This component belongs to the SAM4S family of Flash microcontrollers based on the ARM Cortex-M4 core. The series offers scalable memory options and diverse peripheral sets suitable for various embedded applications. The ATSAM4S2BB variant specifically provides 128 KB of Flash, positioning it between lower-capacity and higher-end models in the lineup.
Replacement Considerations
Check for direct pin-compatible substitutes within the SAM4S family such as ATSAM4S2BC or ATSAM4S2BD. Verify that any replacement maintains the same package type and electrical specifications. Consult official cross-reference lists for validated alternatives.
