Procurement Notes

Verify the suffix CFUR indicates tape and reel packaging when sourcing components. Confirm the specific temperature grade and RoHS compliance status against the latest manufacturer datasheet prior to procurement. Ensure compatibility with existing PCB footprints for the 100-VFBGA package.

Selection Notes

Select this model for designs requiring 1 MB of program memory and 160 KB of RAM in a compact BGA form factor. Compare with ATSAM4SA16CA-CFU if tray packaging is preferred over reel packaging. Consider the ATSAM4SD series if NAND flash integration is required instead of standard SRAM.

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 mid-range applications balancing power consumption and processing performance. The 'A' variant typically denotes industrial temperature ranges and enhanced reliability features compared to commercial grades.

Replacement Considerations

ATSAM4SA16CA-CFU serves as the tray-packaged equivalent. ATSAM4S16CA-CFU is a similar core variant but may differ in specific peripheral configurations or memory sizes depending on the exact revision. Verify pin-to-pin compatibility before substitution.
