Procurement Notes
Verify the specific suffix 'AN' against official Microchip documentation to confirm temperature grade and packaging details. Ensure compatibility with existing PCB footprints for the 100-pin LQFP package. Cross-reference pin assignments with the latest datasheet revision to avoid interface mismatches during integration.
Selection Notes
Select this component when both high computational power and extensive non-volatile memory are required. Consider the integrated peripherals to reduce external component count. Evaluate power consumption requirements against the available low-power modes. Confirm that the operating voltage range aligns with the system's power supply design.
Part Context
This model belongs to the SAM4S family of microcontrollers, which are designed for cost-sensitive applications requiring ARM Cortex-M4 performance. The series emphasizes connectivity and security for embedded systems. The ATSAM4SA variant typically offers enhanced memory configurations compared to standard SAM4S models, targeting more complex application workloads.
Replacement Considerations
Check Microchip's official cross-reference tools for direct pin-to-pin compatible alternatives within the SAM4S or SAM4E families. Verify that any substitute maintains the same Flash and SRAM capacities. Ensure peripheral compatibility, particularly for Ethernet and USB interfaces, before finalizing any substitution decision.
