Procurement Notes
Verify the specific ordering suffix against official Microchip documentation to confirm package type, temperature grade, and carrier format. 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 a balance of moderate memory capacity and advanced peripheral integration is required. It is suitable for designs needing robust security features like PDID alongside capacitive touch capabilities. Consider the 28-pin form factor for space-constrained PCB layouts while maintaining access to essential communication interfaces.
Part Context
This part belongs to the AVR DA(S) family, which offers vertical migration without code modification across different pin counts and memory sizes. It shares architectural similarities with other AVR DA devices but is distinct in its specific 32 KB Flash and 28-pin configuration. The family emphasizes low-power operation and high-performance digital peripherals.
