Procurement Notes
Verify the specific suffix 'S' against the official datasheet to confirm packaging or variant distinctions. Ensure the operating temperature range meets application requirements. Confirm RoHS compliance status through manufacturer documentation before integration into production designs.
Selection Notes
Select this model when 64 kB flash and 8 kB RAM are sufficient for code size. The 24 MHz speed balances performance and power consumption. Consider the 48-pin TQFP footprint for PCB layout constraints. Evaluate peripheral counts against system interface requirements.
Part Context
This part belongs to the AVR DA series, which combines high-performance AVR cores with advanced analog peripherals. The series targets applications needing real-time control and smart analog features in a compact form factor, offering flexibility for both standalone and companion MCU roles.
Replacement Considerations
Check for pin-compatible alternatives within the AVR DA family, such as AVR64DA32 or AVR64DA64 variants, depending on memory and I/O needs. Verify software compatibility if migrating between different memory densities within the same series.
FAQ
What does the PDID feature provide?
Peripheral Direct Interface (PDID) allows peripherals to communicate directly without CPU intervention, reducing processor load and improving response times for time-critical tasks.
Is the AVR64DA48S-E/PT suitable for AC mains applications?
Yes, it includes three Zero-Crossing Detection (ZCD) modules specifically designed for detecting AC mains zero-crossings, making it suitable for lighting and motor control applications.
