Procurement Notes

Verify the specific suffix 'CUR' against the manufacturer's official datasheet to confirm the exact package type, temperature grade, and tape-and-reel configuration. Ensure that the ordering information matches the required industrial temperature range and RoHS compliance status documented in the product specification sheet before finalizing procurement.

Selection Notes

Select this component when a 32-bit architecture is required with moderate memory capacity. The 48 MHz speed and 1.8V to 3.6V operating range suit applications needing balanced performance and power efficiency. Compare pin counts and interface availability against alternative SAM3N variants to ensure compatibility with the target circuit design constraints.

Part Context

This part belongs to the Microchip SAM3N family, designed for cost-sensitive applications. It shares the Cortex-M3 core architecture with other SAM3 series devices but differs in memory size and interface options. The TFBGA-100 package provides a compact footprint suitable for space-constrained designs compared to larger QFP packages in the same family.

Replacement Considerations

Consult the official cross-reference guide for direct substitutes. Verify pin-to-pin compatibility and electrical specifications if considering alternatives from the same manufacturer or other vendors.
