Procurement Notes
Verify that the specific suffix AUT corresponds to the required automotive grade and temperature rating during procurement. Confirm package type and tape-and-reel specifications match assembly requirements. Ensure compatibility with existing design infrastructure regarding voltage levels and pin configurations before finalizing orders.
Selection Notes
Select this component when automotive certification is mandatory for the application. Choose this model over non-automotive variants if long-term availability and thermal stability are critical. Consider the 48 MHz performance limit and memory size relative to software complexity. Evaluate pin count adequacy for required I/O and peripheral connections.
Part Context
This part belongs to the ATSAMC21 family of 32-bit microcontrollers designed for cost-sensitive embedded applications. The G16 variant specifically denotes 64 kB of Flash memory. The AUT suffix indicates automotive qualification and a specific operating temperature range. It shares architectural similarities with other SAMD and SAMC series devices but offers enhanced reliability features.
Replacement Considerations
Direct substitutes within the same family include ATSAMC21G16A-ANU for higher temperature ratings or ATSAMC21G16A-MUT for different packaging. Cross-family replacements require careful evaluation of pin compatibility and peripheral differences.
