• Includes Configurable Custom Logic (CCL) with programmable Look-up Tables
• Supports secure firmware upgrades via Program and Debug Interface Disable (PDID)

Applications

• Capacitive touch interface designs
• Power control systems utilizing Timer/Counter type D
• Industrial communication networks requiring multiple serial interfaces

Procurement Notes

Verify the specific ordering suffix 'T' indicates tape and reel packaging when sourcing components. Confirm the '-I' designation aligns with required industrial temperature specifications. Ensure compatibility with existing design tools and verify that the 48-pin TQFP footprint matches the target PCB layout constraints before finalizing procurement.

Selection Notes

Select this component for projects requiring vertical migration within the AVR DA family without code modification. It is suitable for designs needing high pin counts with extensive peripheral integration in a compact form factor. Consider its multi-voltage I/O capabilities and low-power architecture for energy-efficient embedded applications.

Part Context

This part belongs to the AVR32DA28/32/48(S) series, which shares architectural similarities with other devices in the AVR DA family. It offers horizontal migration options to reduce pin counts or vertical expansion to larger memory variants while maintaining pin and feature compatibility across the series.
