Procurement Notes

Verify the specific suffix 'AUR' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the operating temperature range meets the environmental specifications of the target application. Ensure compatibility with the intended development tools and software frameworks provided by the manufacturer for the SAM3N series.

Selection Notes

Select this component when a balance between processing capability and pin count is required for compact designs. The 48-pin LQFP package suits space-constrained applications. Consider the 48MHz clock speed sufficient for moderate computational loads. Evaluate the available I/O count against interface requirements before choosing alternative pin counts within the same family.

Part Context

This part belongs to the Microchip SAM3N series, designed for cost-sensitive embedded applications. It utilizes the ARM Cortex-M3 architecture to deliver performance while maintaining low power usage. The series is characterized by its integration of essential peripherals and support for various communication standards suitable for general-purpose microcontroller tasks.

Replacement Considerations

The ATSAM3N1AB-AU serves as a non-reel variant of the same silicon specification. Cross-reference pinouts and electrical characteristics when substituting with other SAM3N models to ensure functional compatibility.
