Procurement Notes

Verify the suffix 'AUTR' indicates tape and reel packaging distinct from tray versions. Confirm the specific revision level matches project requirements. Check RoHS compliance status via official documentation. Ensure ESD handling procedures are followed during assembly. Validate pinout compatibility with existing PCB layouts.

Selection Notes

Select this model when 512 kB flash and 152 kB RAM are required alongside cryptographic features. The 20 MHz speed suits applications not demanding higher frequencies. Compare against ATSAM4C8CB-AUT if tray packaging is preferred. Consider power consumption profiles relative to other SAM4C variants.

Part Context

This part belongs to the SAM4C series of high-performance 32-bit MCUs based on the ARM Cortex-M4 core. The series emphasizes security and connectivity for embedded applications. The ATSAM4C8CB variant specifically offers mid-range memory capacity within the family.

Replacement Considerations

ATSAM4C8CB-AUT serves as a direct functional substitute differing primarily in packaging format.
