Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm that the 'R' suffix indicates reel packaging if required by assembly processes. Ensure compatibility with existing design constraints regarding voltage levels and pin configurations before finalizing procurement.
Selection Notes
Select this component when dual-bank Flash memory and a 2 KB cache are required for high-performance applications. It is suitable for designs needing extensive connectivity through HS SDIO and FS USB alongside rich analog interfaces. Consider its pin-to-pin compatibility with SAM4N, SAM3S, and SAM7S series for migration purposes.
Part Context
This part belongs to the SAM4S series of microcontrollers from Microchip Technology. The series is designed to offer scalable performance and power efficiency, extending the portfolio of Cortex-M-based MCUs. It provides a balance of processing speed, memory density, and peripheral richness for embedded applications.
Replacement Considerations
Pin-to-pin compatible alternatives within the same family include ATSAM4SD16CA-ANR and ATSAM4SD16BA-AU. Verify package dimensions and thermal characteristics when substituting between BGA, LQFP, or QFN variants.
