Procurement Notes
Verify the specific suffix 'AUR' indicates tape-and-reel packaging when ordering. Confirm the manufacturer part number matches exactly to ensure correct pinout and electrical characteristics. Check current availability status as lead times may vary. Ensure compatibility with existing PCB footprints for the 64-LQFP package before finalizing procurement decisions.
Selection Notes
Select this model when 1MB of flash and 128KB of RAM are required within a compact 64-pin form factor. It is suitable for designs needing integrated USB functionality without external transceivers. Consider the 120MHz clock speed for applications demanding moderate computational performance. Verify that the industrial temperature range meets environmental requirements.
Part Context
This component belongs to the SAM4S family of 32-bit microcontrollers based on the ARM Cortex-M4 architecture. The series is designed for cost-sensitive applications requiring good performance and rich peripheral sets. The ATSAM4S16BA variant specifically offers 1MB of flash memory, distinguishing it from lower-capacity models in the same package.
Replacement Considerations
ATSAM4S16BA-AU is the tray-packaged equivalent of this reel-part. Other SAM4S variants with different memory sizes or pin counts may serve as functional alternatives if interface requirements align.
