Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Ensure compatibility with the required voltage levels for VDDCORE and VDDIO during power-up sequences. Confirm that the selected packaging format matches the production requirements for surface mount assembly processes.
Selection Notes
Select this component when an application requires integrated Ethernet and USB host capabilities alongside standard serial interfaces. The SAM3X4 variant provides sufficient memory for complex protocol stacks while maintaining low-power modes. Consider the 100-pin package constraints if board space is limited compared to the 144-pin alternatives.
Part Context
This part belongs to the Atmel SMART SAM3X/A series, designed for high-performance 32-bit processing. The series utilizes a multi-layer bus matrix to maximize data throughput and supports parallel task execution. It is optimized for applications demanding robust connectivity and efficient power management across various industrial and consumer electronics environments.
Replacement Considerations
Consult official substitution lists for equivalent parts within the SAM3X family. Verify pinout compatibility and memory configurations before replacing.
