Procurement Notes
Verify the specific ordering suffix to confirm the package type and temperature range. Ensure compatibility with existing PCB footprints for the 100-pin VFBGA configuration. Confirm that the selected variant meets the required operational temperature specifications for the intended environment. Cross-reference the datasheet revision to ensure all technical parameters align with current manufacturing standards.
Selection Notes
Select this component when a balance of moderate memory density and high processing speed is required. The 100-pin VFBGA package offers a compact solution for space-constrained designs. Consider the availability of development tools like Atmel Studio and evaluation kits to accelerate prototyping. Evaluate power consumption requirements against the dynamic and standby modes specified in the datasheet.
Part Context
This part belongs to the SAM4S family, which provides pin-to-pin compatibility with older SAM3S and SAM7S series devices. This facilitates migration for existing designs while gaining access to enhanced performance and lower power consumption. The series supports scalable memory configurations ranging from 128 KB to 2 MB of Flash.
