- Consumer electronics utilizing USB connectivity and audio processing via DACs
- Medical devices needing precise analog signal acquisition through ADC channels
Procurement Notes
Verify the specific suffix 'MN' against official Microchip documentation to confirm the exact package type and temperature grade, as distributor listings may vary or lack detailed suffix definitions. Ensure compatibility with required operating temperatures and interface configurations before procurement.
Selection Notes
Select this component when a balance of moderate memory capacity and rich peripheral sets is required. The 120MHz speed suits applications needing efficient code execution without the complexity of higher-end cores. Verify that the 64-pin form factor fits the design constraints compared to other SAM4S variants.
Part Context
This part belongs to the SAM4S family, which targets cost-sensitive applications requiring ARM Cortex-M4 performance. The series offers various memory sizes and packages. The ATSAM4S4B variant specifically denotes the 256KB flash configuration within this lineup.
Replacement Considerations
ATSAM4S4BB-AN: Identical electrical specifications but utilizes a 64-LQFP package instead of the QFN form factor implied by some datasheet cross-references for similar suffixes.
