• SERCOM modules providing flexible communication capabilities across multiple protocols
• Advanced motor control peripherals designed for industrial environments

Applications

• Industrial automation systems requiring noise immunity
• Commercial appliances with embedded control logic
• Automotive electronics meeting AEC-Q100 requirements
• Motor control applications utilizing dedicated peripheral sets

Procurement Notes

Verify the specific suffix MNT indicates tape and reel packaging configuration. Confirm the G16 variant corresponds to the 64 kB Flash capacity. Ensure the operating temperature grade matches the +105°C requirement. Check RoHS compliance documentation for environmental regulations. Validate pinout compatibility with existing PCB layouts before integration.

Selection Notes

Select this model when 64 kB of program storage is sufficient for application firmware. Choose the VQFN-48 package for space-constrained surface-mount designs. Opt for this part if AEC-Q100 certification is mandatory for the target market. Consider the 48 MHz processing speed adequate for real-time control tasks. Evaluate the 38 available I/O lines against peripheral connection needs.

Part Context

This component belongs to the SAM C21 family of 5V Cortex-M0+ microcontrollers. The series emphasizes robustness for noisy industrial and commercial environments. It integrates SERCOM, CAN FD, and PTC peripherals for versatile connectivity and user interaction. The family supports functional safety requirements through standardized design principles.

Replacement Considerations

ATSAMC21G16A-AUT: Same core specifications with TQFP-48 package. ATSAMC21G16A-MUT: Same core specifications with QFN-48 package. ATSAMC21G17A-MNT: Higher capacity variant with 128 kB Flash in identical VQFN-48 package.
