• Automotive infotainment and instrument clusters operating in harsh environments

Procurement Notes

Verify the specific suffix 'ANR' corresponds to the tape-and-reel packaging variant of the ATSAM4S4BB series. Confirm that the required pinout and electrical characteristics match the official Microchip datasheet for the SAM4S family. Ensure compatibility with existing design tools and development kits provided by the manufacturer for this specific component.

Selection Notes

Select this component when a balance of high-performance processing and extensive peripheral integration is required. The 256KB flash and 64KB RAM suit complex firmware applications. Consider the 64-pin LQFP package for ease of assembly if surface mount technology allows. Evaluate power requirements against the 1.62V to 3.6V operating range to ensure stable performance across the intended voltage supply.

Part Context

This part belongs to the Microchip SAM4S series of 32-bit microcontrollers. The series is designed for applications demanding high performance and rich peripheral sets. Other variants in the family differ primarily in memory size, package type, and I/O count, while sharing the same Cortex-M4 core architecture and peripheral ecosystem.

Replacement Considerations

Direct substitutes within the same package and pinout may include other SAM4S variants with equivalent or larger memory sizes, such as ATSAM4S4BC or ATSAM4S8C, subject to availability and specific feature requirements. Cross-series replacements require careful verification of software compatibility and peripheral mapping.
