Procurement Notes

Verify the specific ordering suffix 'N' against official documentation to confirm package type and temperature range specifications. Ensure compatibility with existing design constraints regarding the 100-pin VFBGA footprint. Confirm that the selected variant meets all required electrical and environmental standards for the intended application environment before finalizing procurement.

Selection Notes

Select this component when a balance of moderate memory density and high processing speed is required within a compact surface-mount package. Consider the pin-to-pin compatibility with SAM3S and SAM7S legacy products if migration from older architectures is planned. Evaluate the peripheral set, particularly the analog converters and connectivity options, against specific application requirements.

Part Context

This part belongs to the SAM4S family, which extends Microchip's Cortex-M-based MCU portfolio with increased performance and power efficiency. The series offers scalability in memory density up to 2 MB of Flash and supports various packages including QFP, QFN, and BGA types. It is designed to facilitate easy migration within the Microchip portfolio due to its pin-to-pin compatibility with other series.
