Procurement Notes
Verify the specific suffix ANR indicates reel packaging when sourcing components. Confirm the assembly site and date code against current production notices to ensure material compliance. Check for any recent pinning or packaging changes documented in official product change notifications before finalizing procurement plans.
Selection Notes
Select this component when 1MB of program storage and 160KB of RAM are required within a compact 64-pin footprint. The ATSAM4SA16BB-ANR is suitable for designs needing USB functionality without external transceivers. Consider the 120MHz clock speed for applications demanding real-time processing performance within the specified voltage and temperature constraints.
Part Context
This part belongs to the SAM4S family of 32-bit flash microcontrollers based on the ARM Cortex-M4 core. The series is designed for mid-range applications balancing power consumption with processing capability. The ATSAM4SA variant specifically denotes features optimized for general-purpose use with standard peripheral sets found across the broader SAM4S lineup.
Replacement Considerations
Cross-reference with other SAM4S variants sharing the same core and memory size but different packages or temperatures. Verify pin compatibility if substituting with other 64-pin LQFP devices in the same family. Ensure peripheral availability matches the original design requirements when considering alternative part numbers.
