Procurement Notes
Verify the specific suffix CN indicates the standard commercial/industrial grade packaging and material composition as defined by Microchip. Confirm that the 100-TFBGA footprint matches your PCB design constraints. Ensure compliance with RoHS3 directives if required for your target market regulations. Cross-reference the latest datasheet revision for any errata or pinout updates before finalizing procurement.
Selection Notes
Select this component when 1MB of program storage and 160KB of RAM are necessary for complex firmware applications. The 120MHz clock speed supports demanding real-time processing tasks. Choose this model over lower-capacity SAM4S variants if code size exceeds 512KB. The TFBGA package is suitable for high-density board designs where space is limited compared to LQFP options.
Part Context
This part belongs to the SAM4S series of 32-bit microcontrollers designed for cost-sensitive applications requiring high performance. It shares architectural similarities with the SAM3N and SAM3S families, allowing for potential pin-to-pin compatibility in certain configurations. The series emphasizes low power consumption modes alongside high-speed processing capabilities.
Replacement Considerations
Consult the official SAM4S family datasheet for verified pin-compatible alternatives such as ATSAM4SD16CB-CN or ATSAM4SA16CA-CFU. Verify that substitute parts match the required Flash size, RAM capacity, and operating temperature range. Check for any differences in package dimensions or electrical characteristics before implementation.
