- Embedded systems requiring extended temperature operation
Procurement Notes
Verify that the specific suffix corresponds to the required package type and temperature grade. Confirm that the procurement source provides documentation supporting AEC-Q100 compliance. Ensure the ordering information matches the intended operating voltage and speed requirements for the target application environment.
Selection Notes
Select this component when automotive qualification and wide temperature tolerance are mandatory. The 4K Flash capacity suits moderate code complexity applications. Verify that the 16MHz maximum frequency aligns with processing demands. Consider the available I/O lines and ADC channels against peripheral connectivity needs.
Part Context
This part belongs to the ATtiny261/461/861 family of automotive microcontrollers. It shares the core AVR architecture with variants offering different memory sizes. The 'Z' identifier denotes the full automotive temperature range capability. This series targets applications requiring robust performance in demanding electrical and thermal conditions.
Replacement Considerations
Check for other members of the ATtiny261/461/861 family with matching memory sizes. Verify package compatibility if substituting with SOIC or TSSOP versions. Ensure any replacement maintains the required AEC-Q100 certification and temperature range specifications.
