Procurement Notes

Verify the specific suffix 'ANR' against official Microchip documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing PCB footprints for the LQFP-100 or TFBGA-100 variant as specified in the datasheet. Cross-reference lead times and RoHS compliance status directly with authorized distributors prior to procurement.

Selection Notes

Select this component when a balance of processing power and analog integration is required within a compact form factor. Consider the 120MHz clock speed and 256KB Flash capacity for complex firmware execution. Evaluate pin count availability against interface requirements, noting that alternative packages in the SAM4S family may offer different I/O densities.

Part Context

This part belongs to the Microchip SAM4S series, designed for cost-sensitive embedded applications. It shares architectural similarities with other SAM4S variants but differs in memory size and package options. The series targets general-purpose microcontroller needs, offering a scalable platform for developers transitioning from older 8-bit or 16-bit architectures.

Replacement Considerations

Direct substitutes include other ATSAM4S4B variants with differing packages, such as ATSAM4S4CA-AUR or ATSAM4S4CB-CN. Verify electrical specifications and pinout compatibility before substitution. No cross-model generic features should be assumed without verifying individual datasheet parameters.
