Procurement Notes
Verify the specific suffix against official datasheets to confirm package type and temperature range. Ensure compatibility with existing PCB footprints for the 64-QFN configuration. Cross-reference part numbers with manufacturer documentation to avoid substitution errors due to minor variant differences.
Selection Notes
Select this component when 512KB of program storage and 64KB of RAM are required alongside a compact surface-mount package. Consider the 120MHz clock speed for performance needs and verify that the 1.62V to 3.6V supply range matches the system power architecture.
Part Context
This unit belongs to the SAM4S family, designed for cost-sensitive embedded applications. It shares architectural similarities with other SAM4S variants but offers specific memory and pin configurations tailored for balanced performance and interface density in mid-range microcontroller projects.
Replacement Considerations
Consult the SAM4S Series Datasheet for verified substitute part numbers. Direct replacements may require checking for identical memory sizes and package dimensions to ensure mechanical and electrical compatibility without redesigning the host board.
