Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing board layouts for the 24-SSOP form factor. Confirm that the selected variant meets all regulatory requirements for your target market. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this model when 32 KB of program storage and 8 KB of RAM are sufficient for the application firmware. Choose this variant over others in the series if the 24-SSOP package is required for PCB space constraints. Consider the integrated PTC and crypto features if touch interface or security is a primary design requirement.

Part Context

This component belongs to the ATSAML10 family of ultra-low-power microcontrollers designed by Microchip Technology. These devices are optimized for cost-sensitive applications requiring moderate performance and enhanced security features. The SAM L10 series targets markets where power efficiency and data integrity are critical operational factors.

Replacement Considerations

Consult official substitution guides for compatible parts within the ATSAML10 or ATSAML11 families. Verify pinout compatibility and software register mapping before replacing the component.
