Procurement Notes
Verify the specific suffix 'UUR' against official Microchip documentation to confirm it denotes the tape-and-reel packaging variant of the standard ATSAM4SD16BA-AU part. Ensure the ordering code matches the required reel quantity and that the component meets RoHS3 compliance standards for your manufacturing process.
Selection Notes
Select this component when a balance of high-performance computing and extensive onboard memory is required within a compact 64-pin footprint. It serves as a suitable upgrade path for legacy SAM7S designs due to pin compatibility while offering enhanced security features and DSP capabilities not available in previous generations.
Part Context
This MCU belongs to the SAM4S family, which bridges the gap between high-performance application processors and standard microcontrollers. The series is designed for cost-sensitive applications demanding ARM Cortex-M4 performance, featuring hardware acceleration for cryptographic operations and efficient power management across various operational states.
Replacement Considerations
The ATSAM4SD16BA-AU is the tray-packaged equivalent. For direct functional substitution, verify pinout compatibility with other SAM4S variants like the ATSAM4S16BA, noting differences in Flash size and peripheral availability.
