Procurement Notes

Verify the specific suffix 'MN' against official Microchip documentation to confirm temperature range and packaging details. Ensure compatibility with the required voltage levels and clock speeds for your application design. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match your schematic requirements before finalizing procurement.

Selection Notes

Select this component when a balance of processing speed and peripheral integration is required within a compact 24-pin footprint. Consider the available memory sizes and the presence of the touch controller if user interaction is needed. Evaluate the power consumption profiles across different voltage ranges to ensure compliance with system energy constraints.

Part Context

This part belongs to the tinyAVR 1-series family, which emphasizes low power and high performance through core-independent peripherals. The series shares architectural similarities with other members like the ATtiny817, differing primarily in memory capacity and specific package options. It targets cost-sensitive applications needing robust analog and digital capabilities.

Replacement Considerations

Check for direct substitutes within the same tinyAVR 1-series family that offer compatible pinouts and memory configurations. Verify that any alternative part number maintains the required temperature range and package type for your existing board layout.
