Procurement Notes
Verify the specific suffix UUR corresponds to the LQFP package and tape-and-reel delivery format. Confirm the temperature grade matches industrial requirements (-40°C to 85°C). Ensure compatibility with existing PCB footprints for the 100-pin LQFP configuration. Check for any recent Product Change Notifications regarding assembly sites or marking changes.
Selection Notes
Select this component when 1MB of Flash and 160KB of RAM are required alongside external memory controller support. It is suitable for applications needing Ethernet MAC integration and high-speed USB connectivity. Consider the 120MHz performance limit and the specific pin count of the 100-LQFP package against system interface requirements.
Part Context
This part belongs to the SAM4S series of microcontrollers from Microchip Technology. It shares architectural similarities with other SAM4S variants but offers higher memory capacity and additional peripheral sets compared to lower-end models in the same family. The series is designed for applications demanding high performance and rich connectivity.
Replacement Considerations
Direct replacements include other SAM4S series parts with similar memory sizes, such as ATSAM4SD16BA or ATSAM4SD16CB, depending on the required package type. Verify pin compatibility and software register-level differences before substitution.
