Procurement Notes
Verify the specific ordering code ATtiny87-A15MD against official Microchip documentation to ensure correct package type and temperature grade. Confirm that the application environment does not exceed the absolute maximum ratings defined in the datasheet. Ensure compatibility with the required voltage supply range of 4.5V to 5.5V during procurement planning.
Selection Notes
Select this component when automotive reliability and high-temperature operation are critical requirements. The AEC-Q100 Grade 0 qualification ensures suitability for demanding automotive environments. Consider the 32-pin QFN package constraints for PCB layout. Verify that the 8KB Flash and 512B RAM meet the firmware size requirements before finalizing the selection.
Part Context
This part belongs to the ATtiny87/ATtiny167 family of automotive microcontrollers. It is specifically designated for applications requiring robust performance under extreme thermal conditions. The 'A15' suffix indicates the extended temperature range and automotive qualification. It serves as a specialized variant within the broader AVR microcontroller portfolio.
Replacement Considerations
Consult the official datasheet for cross-reference information. Direct replacements must match the AEC-Q100 Grade 0 qualification and 150°C operating temperature limit. Verify pinout compatibility if substituting with other packages like the 6G TSSOP variant.
