Procurement Notes

Verify the specific suffix 'AUR' indicates tape and reel packaging when ordering. Confirm the temperature grade corresponds to industrial specifications (-40°C to +85°C). Ensure compatibility with existing PCB footprints for the 100-VFBGA package. Check for RoHS compliance documentation if required by your manufacturing standards. Validate that the 1.62V to 3.6V supply range matches your system power design.

Selection Notes

Select this component when 1 MB of program memory and 160 kB of RAM are required for complex firmware applications. Choose the ATSAM4SA16BA-AUR over lower-density variants if extensive code storage or large data buffers are necessary. Consider the 120 MHz clock speed for applications demanding high computational throughput. Evaluate the 79 available I/O lines against interface requirements before finalizing the selection.
