Procurement Notes
Verify the exact suffix 'SFR' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure compatibility with your PCB footprint for the 20-SOIC package. Cross-reference the RoHS compliance status directly with Microchip Technology documentation before procurement.
Selection Notes
Select this component when 8 KB of Flash memory is sufficient for application code. Consider the 20-pin SOIC package constraints for board layout. Evaluate the 20 MHz operational speed against system timing requirements. Confirm that the 1.8 V to 5.5 V supply range matches the target power design.
Part Context
This part belongs to the ATtiny416/816 family, which utilizes the high-performance low-power AVR RISC architecture. These microcontrollers are designed for applications requiring efficient code execution and minimal power usage. The family shares common peripheral sets and instruction sets, facilitating migration between variants within the series.
Replacement Considerations
Consult Microchip Technology's official cross-reference tools for verified substitutes. Ensure any replacement maintains the 20-pin SOIC package and compatible voltage ranges. Verify pinout compatibility to avoid redesigning the host circuit board.
