• Smart metering applications utilizing zero-crossing detection.
• IoT devices needing secure boot and data integrity.
• Home appliance controllers with multi-voltage interface requirements.

Procurement Notes

Verify the specific suffix 'S' in the part number against official Microchip documentation to confirm packaging or variant distinctions. Ensure the operating temperature grade matches the industrial specification (-40°C to +85°C). Cross-reference the datasheet revision to confirm peripheral availability and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when a balance of moderate code capacity and advanced analog features is required. The 32 kB Flash size suits applications with complex logic but limited memory needs. Consider the 24 MHz speed for real-time processing tasks. Evaluate the pin count against interface requirements, noting the availability of multiple communication ports and analog inputs on the 48-pin package.

Part Context

This part belongs to the AVR32 DA series, which targets cost-sensitive applications requiring enhanced analog capabilities and security. It shares architectural similarities with other AVR DA models but offers specific memory and pin configurations. The series emphasizes low power consumption and ease of integration into compact embedded designs.

Replacement Considerations

Check for AVR32DA48-I/PT if the 'S' suffix denotes a specific packaging variation rather than a functional difference. Verify compatibility with AVR64DA48-I/PT if additional memory is acceptable. Ensure pinout and peripheral mapping remain consistent during substitution to avoid PCB redesign.
