Procurement Notes
Verify the exact suffix against official Microchip documentation to confirm pin compatibility and thermal specifications. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the datasheet revision date to account for any silicon errata or design clarifications that may impact integration.
Selection Notes
Select this model when 256KB of program storage and 64KB of RAM are sufficient for the application logic. The TFBGA package is suitable for high-density PCB layouts. Consider the 120MHz clock speed relative to power consumption constraints. Verify that the 1.62V minimum supply voltage aligns with the system power architecture.
Part Context
This component belongs to the SAM4S family of microcontrollers designed for cost-sensitive embedded applications. It shares architectural similarities with other SAM4S variants but differs in memory size and package type. The series is widely used in industrial and consumer markets due to its balance of performance and peripheral richness.
Replacement Considerations
ATSAM4S4CB-CN provides identical electrical characteristics in a different package. ATSAM4S4CA-CU offers the same functionality in a TFBGA format with potentially different marking. Verify pinout compatibility before substitution.
