Procurement Notes

Verify the specific suffix 'CU' corresponds to the TFBGA-100 package and industrial temperature grade (-40°C to +85°C) in the official datasheet. Confirm that the 1.62 V to 1.95 V supply voltage range aligns with your system design, as this differs from other variants in the SAM4N family. Ensure compatibility with the required pin count and interface availability for your application before procurement.

Selection Notes

Select this component when a balance of performance and pin count is needed for cost-sensitive applications. The 100-pin TFBGA package offers a compact footprint suitable for space-constrained designs. Consider the 100 MHz speed and 1 MB Flash capacity for complex firmware requirements. Compare against the ATSAM4N16BA-AUR if reel packaging or different thermal characteristics are required.

Part Context

The ATSAM4N16CA-CU belongs to the SAM4N series, designed for high-performance, low-cost applications. It shares architectural similarities with the SAM3N and SAM3S series, offering pin-to-pin compatibility in certain configurations. This series targets markets such as smart meters, industrial controls, and consumer electronics where efficiency and integration are critical.

Replacement Considerations

Public confirmed substitute part numbers: ATSAM4N16BA-AUR (Reel packaging variant). Verify package type and operating temperature range differences before substitution.
