Procurement Notes
Verify the ordering code suffix matches the required speed grade and package type. Confirm the temperature range corresponds to the specific application environment requirements. Ensure the supply voltage levels align with the specified operational limits for the selected clock frequency. Check for any specific revision errata relevant to the manufacturing batch.
Selection Notes
Select this component when high performance per MHz is required alongside low power consumption. Consider the 16K Flash size for complex applications. Evaluate the need for capacitive touch sensing capabilities. Verify that the 20-pin MLF package fits the board layout constraints. Ensure the operating voltage range covers the system's minimum and maximum supply conditions.
Part Context
This part belongs to the ATtiny1634 series within the Atmel AVR family. It is designed for applications needing a balance of processing power and energy efficiency. The device utilizes high-density non-volatile memory technology. It is supported by a comprehensive suite of development tools including compilers and debuggers.
Replacement Considerations
ATtiny1634-MU: Same specifications but in SOIC-20 package. ATtiny1634-SU: Same specifications but in SOIC-20 package with different temperature rating.
