Procurement Notes
Verify the specific package variant and tape-and-reel quantity requirements against the official datasheet before ordering. Confirm that the selected part number matches the required automotive grade and temperature specifications. Ensure compatibility with existing design tools and programming interfaces. Check for any recent revisions to the component documentation that may affect pinout or electrical characteristics.
Selection Notes
Select this component when automotive reliability and functional safety are primary requirements. The integrated touch controller reduces external component count for UI designs. Consider the 48 MHz performance limit and memory size for application complexity. Evaluate the available I/O count and peripheral set against system connectivity needs. Compare with other SAM DA1 variants if different memory or package options are required.
Part Context
This microcontroller belongs to the SAM DA1 family, which is designed specifically for automotive applications. The family shares common architectural features but varies in memory size and package options. The ATSAMDA1E16B-ABT provides a balanced combination of processing power and peripheral integration for mid-range automotive control tasks.
Replacement Considerations
Check for direct substitutes within the SAM DA1 family such as the ATSAMDA1G16B series. Verify pin-to-pin compatibility and software library support before substitution. Ensure the alternative part meets the same AEC-Q100 qualification level.
