Procurement Notes
Verify the specific suffix 'CN' versus 'CU' against official datasheets, as these often denote temperature ranges or packaging variations. Confirm RoHS compliance status through current manufacturer documentation. Ensure pin compatibility with existing designs if substituting from similar SAM4S variants.
Selection Notes
Select this component when 1MB of program storage and 160KB of RAM are required in a compact TFBGA form factor. The internal oscillator and power management features simplify board design. Evaluate thermal performance for industrial temperature ranges if operating outside commercial limits.
Part Context
This part belongs to the SAM4S family, designed for cost-sensitive applications needing Cortex-M4 performance. It offers pin-to-pin compatibility with SAM3N and SAM3S series devices, facilitating migration paths for legacy designs while upgrading processing capabilities and memory capacity.
Replacement Considerations
ATSAM4SD16CB-CN serves as a verified alternative with identical electrical specifications but utilizes a different package type.
