• Automotive-grade qualification ensuring reliability in noisy environments

Applications

• Industrial control systems requiring robust communication
• Commercial applications operating in electrically noisy environments
• Motor control implementations utilizing advanced peripherals

Procurement Notes

Verify the specific suffix 'ANT' corresponds to the TQFP-64 package and industrial temperature grade (-40°C to +105°C). Confirm that the AEC-Q100 qualification aligns with project requirements. Ensure compatibility with the 5V operation range specified for the SAM C21 series. Cross-reference the datasheet for pinout details to validate PCB layout constraints.

Selection Notes

Select this component when a 64 kB flash size and 52 I/O count are required within a TQFP-64 footprint. It is suitable for designs needing automotive-grade reliability without higher pin counts. Compare against the ATSAMC21J17A if additional memory or I/O resources are necessary. Consider the ATSAMC21G17A if a smaller TQFP-48 package is preferred for space-constrained applications.
