• Industrial control systems utilizing core-independent peripherals
• Smart home appliances with capacitive touch interface requirements
• Automotive applications compatible with automotive-grade temperature ranges

Procurement Notes

Verify the specific speed grade and temperature range options available for the ATTINY814-SSN suffix against the official Microchip ordering guide. Confirm that the 14-pin SOIC package dimensions match your PCB footprint requirements. Ensure compliance with RoHS directives if required for your manufacturing process. Check for any recent lifecycle status updates or recommended replacement parts on the manufacturer's website.

Selection Notes

Select this component when an 8-bit AVR architecture with up to 8KB Flash is required. Consider the ATTINY814-SSN for designs needing integrated capacitive touch sensing without external controllers. Evaluate the 20MHz performance capability against your processing needs. Verify that the 12 I/O lines and available communication interfaces meet your system connectivity requirements.

Part Context

The ATTINY814-SSN belongs to the Microchip tinyAVR 1-Series family, which emphasizes low power and high performance. This series utilizes the AVR RISC architecture and integrates picoPower technology. The 14-pin package variant offers a compact solution for space-constrained applications while maintaining a rich set of peripherals and memory resources.

Replacement Considerations

Consult the official Microchip documentation for direct pin-compatible replacements within the ATtiny214/414/814 family. Verify memory size differences between variants like ATtiny414 or ATtiny214 if cost optimization is needed. Ensure software compatibility when migrating between different flash capacities within the same series.
