Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature rating. Ensure compatibility with existing design constraints before procurement. Confirm that the 'E' designation matches the required extended temperature range specifications for your application environment.

Selection Notes

Select this component when extended industrial temperature performance is required alongside standard AVR EA features. The 32-pin configuration offers a balance between pin count and memory capacity. Consider the T suffix for tape and reel manufacturing processes if high-volume production is planned.

Part Context

This part belongs to the AVR64EA28/32/48 series, which shares a common architecture across different pin counts and memory sizes. Devices in this family are fully pin and feature compatible, allowing for vertical migration without code modification. The AVR64EA32 specifically targets applications needing 64 KB of Flash in a compact 32-pin form factor.
