Procurement Notes
Verify the specific suffix AN indicates the standard commercial/industrial grade packaging and temperature range. Confirm the 64-LQFP footprint matches your PCB design constraints. Check current datasheet revisions for any errata related to USB or flash programming sequences before finalizing production orders.
Selection Notes
Select this model when 256 KB of program storage and 64 KB of RAM are sufficient for application logic. Choose the LQFP package if through-hole compatibility or specific thermal dissipation requirements dictate its use over QFN alternatives. Ensure system voltage remains within the 1.62 V to 3.6 V operational window for stable performance.
Part Context
This component belongs to the SAM4S family, designed for applications balancing cost and performance. It shares architectural similarities with other SAM4S variants but differs in memory size and package type. The series emphasizes energy efficiency and peripheral richness for embedded control tasks.
Replacement Considerations
ATSAM4S4BA-AU offers similar specifications in a QFN package. ATSAM4S4CA-CU provides increased I/O count in a TFBGA format. Verify pinout compatibility and memory configuration before substituting.
