Procurement Notes
Verify the specific suffix MNT indicates tape and reel packaging when ordering. Confirm the AEC-Q100 qualification status if automotive compliance is required. Ensure the 48-VQFN footprint matches the PCB design. Check for any recent product change notices regarding assembly or material changes from Microchip Technology.
Selection Notes
Select this model for designs requiring 64 KB of program memory and robust industrial interface support. Compare against the ATSAMC21E15A series if lower memory capacity suffices. Consider the package size constraints relative to other SAM C21 variants. Verify power supply requirements align with the 2.7 V to 5.5 V operational range.
Part Context
This component belongs to the Microchip SAM C21 family of 32-bit MCUs. These devices are optimized for industrial and commercial applications in noisy environments. The family emphasizes robust communications peripherals and advanced motor control capabilities. They utilize the ARM Cortex-M0+ processor for efficient code execution.
Replacement Considerations
ATSAMC21E16A-AUT offers the same specifications in TQFP-32 packaging. ATSAMC21G16A-MNT provides similar performance in a 48-VQFN package. Verify pin compatibility and package dimensions before substituting.
