Procurement Notes
Verify that the specific suffix corresponds to the required package type and temperature grade. Confirm that the ordering information matches the intended application environment. Ensure compatibility with existing development tools and programming interfaces before finalizing procurement decisions.
Selection Notes
Select this component when automotive reliability and wide operating temperature ranges are required. Consider the 16MHz speed capability at higher voltages for performance-critical tasks. Evaluate the available I/O count and ADC channels against system interface requirements.
Part Context
This part belongs to the ATtiny261/461/861 family of automotive microcontrollers. It shares architectural similarities with other AVR devices but is specifically qualified for automotive applications. The family offers scalable memory options while maintaining a consistent pinout and peripheral configuration.
Replacement Considerations
Check for direct substitutes within the ATtiny261 series or compatible AVR families. Verify pin compatibility and memory size equivalence. Ensure replacement parts meet the same automotive qualification standards.
