Procurement Notes

Verify the specific suffix 'S' in the part number against official Microchip documentation to confirm any distinct manufacturing or testing variations compared to standard variants. Ensure the SPDIP-28 package type matches your PCB footprint requirements. Confirm that the industrial temperature grade (-40°C to +85°C) aligns with your operational environment specifications before finalizing procurement.

Selection Notes

Select this component when a balance of moderate memory capacity and rich analog peripherals is required in a through-hole package. The 24 MHz speed and 1.8 V minimum voltage make it suitable for battery-powered or low-voltage industrial applications. Compare against other AVR DA series members if higher memory or different pin counts are needed.

Part Context

This part belongs to the AVR32DA family, which integrates advanced analog features into the classic AVR architecture. The DA series distinguishes itself by offering on-chip op-amps and high-resolution converters alongside standard digital peripherals. The AVR32DA28S variant specifically targets applications needing compact 28-pin packaging with enhanced analog performance capabilities.
