Procurement Notes
Verify the specific suffix CFNR against official Microchip documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the component matches the required industrial temperature grade and pinout compatibility for your PCB design. Cross-reference the latest datasheet revision to confirm any errata or silicon updates affecting functionality.
Selection Notes
Select this model when 1 MB of program storage and 160 KB of RAM are required within a compact 100-pin footprint. It is suitable for designs needing integrated USB functionality alongside high-resolution analog inputs. Consider the 120 MHz performance ceiling and available GPIO count relative to system complexity before finalizing the part choice.
Part Context
This component belongs to the SAM4S series of microcontrollers, which are designed for cost-sensitive applications requiring ARM Cortex-M4 performance. The series offers pin-to-pin compatibility with previous generations like SAM3N and SAM3S, facilitating migration paths for existing hardware designs while upgrading processing capabilities.
Replacement Considerations
ATSAM4SA16CA-CFU is a verified alternative in QFN-100 packaging. ATSAM4S16CB-CN is another option in TFBGA-100 packaging but operates at a reduced 48 MHz clock speed.
