Procurement Notes
Verify the specific ordering suffix 'XUR' corresponds to the TSSOP-20 package and industrial temperature range (-40°C to +85°C). Confirm that the datasheet revision matches the required specifications for your design. Ensure compatibility with existing toolchains and programming interfaces before finalizing procurement.
Selection Notes
Select this component when a balance of processing power and peripheral richness is needed in a compact 20-pin form factor. The tinyAVR 2 architecture offers vertical migration within the family without code modification. Consider the 12-bit ADC and event system for applications requiring precise analog signal acquisition and deterministic timing.
Part Context
This part belongs to the tinyAVR 2 family, which shares architectural similarities with other members like the ATtiny426 and ATtiny427. These devices are designed for pin-to-pin compatibility across different pin counts and memory sizes, facilitating easy upgrades or downgrades in product designs while maintaining software compatibility.
Replacement Considerations
Direct replacements within the same package and feature set include the ATtiny426-XUR and ATtiny427-XUR. Verify that the alternative part number meets the specific memory size requirements and peripheral availability needed for the application.
