Procurement Notes

Verify the specific suffix 'CFU' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing design constraints regarding pinout and electrical specifications before procurement. Cross-reference with current datasheets for any recent engineering change notices or lifecycle status updates.

Selection Notes

Select this component when a balance of processing power and memory capacity is required within a compact form factor. Consider the 100-pin TFBGA package for space-constrained designs. Evaluate peripheral requirements such as ADC resolution and interface availability against application needs. Compare performance metrics with other SAM4N variants if higher clock speeds or different memory sizes are necessary.

Part Context

This part belongs to the SAM4N series of 32-bit microcontrollers designed for cost-sensitive applications. It shares architectural similarities with other SAM4 family members but offers specific memory and peripheral configurations tailored for embedded control tasks. The series is known for low power consumption and high performance relative to its class.

Replacement Considerations

Consult official substitution lists for compatible parts within the SAM4N family. Verify pin-to-pin compatibility and software compatibility if replacing with variants like ATSAM4N16BA-AUR. Ensure that any substitute meets the same electrical and environmental specifications.
