Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type, temperature grade, and carrier configuration. Ensure compatibility with existing design constraints regarding pinout and memory size before procurement. Cross-reference datasheet DS40002311A for precise electrical characteristics and operating conditions.

Selection Notes

Select this component for designs requiring vertical migration within the tinyAVR 2 family without code modification. Consider the 14-pin SOIC package for space-constrained applications needing 12 general-purpose I/O pins. Evaluate the extended temperature range suitability for harsh environments and verify power supply requirements align with the 1.8V to 5.5V operational window.

Part Context

This device belongs to the tinyAVR 2 family, which offers horizontal and vertical migration paths across different pin counts and memory sizes. The ATtiny824 shares architectural similarities with other members like the ATtiny424 and ATtiny826, facilitating scalable development. It utilizes the Unified Program and Debug Interface (UPDI) for programming and debugging.

Replacement Considerations

Direct substitutes include other members of the tinyAVR 2 family such as ATtiny824-MFR or ATtiny824-XFR, provided pin and feature compatibility is maintained. Verify that alternative packages meet the same thermal and electrical specifications required by the application.
