Procurement Notes
Verify the specific suffix 'SNR' against the manufacturer's official documentation to confirm the reel or cut tape packaging configuration. Ensure that the SOIC-14 package dimensions and pinout match the target PCB footprint requirements. Confirm compliance with RoHS directives and check for any specific automotive qualification status if required by the application environment.
Selection Notes
Select this component when an 8-bit AVR solution with 8 kB flash and 14 I/O pins is required. Consider the 20 MHz processing speed and 1.8 V to 5.5 V operating range for compatibility with existing power rails. Evaluate the availability of the SOIC-14 package against space constraints and thermal dissipation needs compared to alternative packages like QFN.
Part Context
This part belongs to the ATtiny series of 8-bit microcontrollers, designed for low-cost and low-power applications. It shares architectural similarities with other members of the family but is distinguished by its specific memory size and I/O count. The SNR suffix typically denotes a specific packaging variant within the product line.
Replacement Considerations
Consult official cross-reference lists for direct substitutes. Verify pin-to-pin compatibility and electrical specifications before replacing with other ATtiny models or competing 8-bit MCUs.
