Procurement Notes
Verify the specific suffix CFU corresponds to the 100-VFBGA package and industrial temperature range during procurement. Confirm RoHS compliance status as per current Microchip documentation. Ensure ESD handling procedures are followed due to moisture sensitivity level 3 classification. Cross-reference assembly location notices for any recent manufacturing site changes that may affect lead times or specifications.
Selection Notes
Select this component when a balance of high-performance computing and extensive memory is required within a compact footprint. The inclusion of an internal voltage regulator simplifies power supply design compared to variants requiring external regulation. Consider the VFBGA package constraints regarding PCB layout and thermal dissipation requirements relative to available board space and cooling solutions.
Part Context
This part belongs to the SAM4S series of microcontrollers, which are designed for cost-sensitive applications requiring Cortex-M4 performance. It shares pin compatibility with previous generations like SAM3N and SAM3S in certain packages, facilitating migration paths. The series emphasizes energy efficiency and peripheral integration suitable for embedded control tasks.
Replacement Considerations
ATSAM4SA16CA-CFU offers similar specifications but may differ in specific errata or minor feature sets; verify datasheet details. ATSAM4SD16CB-CN provides the same core functionality in a TFBGA package, requiring schematic and layout adjustments for pinout differences.
