Procurement Notes
Verify the specific suffix 'AUR' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the 100-VFBGA footprint matches the target PCB design constraints. Ensure compatibility with the 1.62V to 3.6V power supply rails in the final application circuit before procurement.
Selection Notes
Select this component when a balance of high memory capacity and moderate pin count is required. The VFBGA package offers a compact solution for space-constrained designs compared to LQFP alternatives. Consider the internal oscillator accuracy if precise timing without external crystals is necessary for the application requirements.
Part Context
This part belongs to the SAM4S family, which provides enhanced performance over previous generations. It shares architectural similarities with other SAM4S variants but differs in memory size and package type. The 'SA' designation typically indicates specific memory configurations within the broader SAM4S product line.
Replacement Considerations
Direct substitutes include ATSAM4SA16CA-AU (tray packaging) or ATSAM4SA16CA-CFU (different BGA variant). Verify pinout compatibility and thermal characteristics when considering alternative packages within the same memory configuration family.
