Procurement Notes
Verify the specific suffix CUR indicates tape-and-reel packaging when sourcing components. Confirm the manufacturer part number matches exactly to ensure compatibility with existing designs. Check for any recent Product Change Notices regarding marking or assembly site changes. Ensure the supplier provides valid traceability documentation for quality assurance purposes.
Selection Notes
Select this component when a balance of high memory capacity and moderate pin count is required. Consider the TFBGA package constraints for PCB layout and thermal management. Evaluate the need for the specific 160 KB SRAM size against alternative SAM4S variants. Ensure the design supports the 1.62 V to 3.6 V supply voltage requirements for stable operation.
Part Context
This microcontroller belongs to the SAM4S family, which is based on the ARM Cortex-M4 architecture. The series is designed for applications demanding high performance and low power consumption. It offers pin-to-pin compatibility with other SAM4S variants, facilitating design scalability across different product lines.
Replacement Considerations
ATSAM4SA16CA-AU: Same specifications in LQFP-100 package. ATSAM4SA16CA-CU: Same specifications in TFBGA-100 package but trayed. ATSAM4SA16CA-CFU: Same specifications in VFBGA-100 package.
