Procurement Notes
Verify the specific suffix 'ST' indicates tape and reel packaging when ordering. Confirm the '-E' grade corresponds to the extended industrial temperature range (-40°C to +125°C). Ensure the VQFN-64 footprint matches your PCB design constraints. Cross-reference the datasheet for exact pinout definitions and electrical characteristics relevant to your application environment.
Selection Notes
Select this model if your design requires high I/O count (55 available) in a compact VQFN package. Consider the AVR DA series architecture for its combination of real-time control and smart analog features. Evaluate the 24 MHz performance against your processing requirements. Compare memory sizes with other variants in the AVR64DA family if different pin counts or storage capacities are needed.
Part Context
This component belongs to the Microchip AVR DA series, which combines 8-bit AVR cores with advanced peripheral integration. The series targets applications demanding both computational power and analog precision. The AVR64DA64 variant specifically offers 64 KB of Flash, balancing cost and capacity for mid-range embedded systems.
Replacement Considerations
Check for availability of AVR64DA64-I/5LX for commercial temperature grades. Consider AVR64DA48T-E/6LX if fewer pins suffice. Verify pin compatibility with existing designs before substituting.
