Procurement Notes
Verify the specific suffix 'CFN' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 100-TFBGA (9x9) configuration. Check for RoHS compliance status and moisture sensitivity level requirements during storage and handling. Confirm availability through authorized distributors as lead times may vary.
Selection Notes
Select this component when a balance of moderate Flash capacity and high-speed processing is required. The 120 MHz Cortex-M4 core suits applications needing efficient code execution. Consider the 100-pin TFBGA package for space-constrained designs. Evaluate peripheral needs such as USB and ADC channels against project specifications before finalizing the choice.
Part Context
This part belongs to the SAM4S family of Flash microcontrollers based on the ARM Cortex-M4 architecture. The series offers scalable memory options and diverse interface sets. The ATSAM4S2CB variant specifically targets applications needing 128 KB of program memory. It shares architectural similarities with other SAM4S parts while differing in memory size and package options.
Replacement Considerations
Consult the SAM4S Series Datasheet for pin-compatible alternatives within the same family. Verify that substitute parts match the 128 KB Flash and 64 KB SRAM configuration. Ensure the replacement maintains the 100-TFBGA package and extended temperature range if required.
