Procurement Notes

Verify the specific suffix 'CB' against official Microchip documentation to confirm package type and temperature grade alignment. Ensure compatibility with existing PCB footprints for the 100-LQFP form factor. Cross-reference RoHS compliance status with current manufacturing notices. Confirm that the selected variant matches the required memory configuration and interface availability for the target design.

Selection Notes

Select this component when dual-core isolation between application and safety-critical tasks is necessary. The SAM4CM series offers higher performance than single-core alternatives while maintaining low power consumption. Evaluate the need for the integrated LCD controller if display integration is required. Consider the 120MHz operation speed relative to system latency requirements and thermal dissipation capabilities within the enclosure.

Part Context

This part belongs to the SAM4CM family, designed for applications requiring robust performance and security. The series distinguishes itself through its dual-core Cortex-M4 architecture, enabling efficient task partitioning. It serves as an upgrade path for designs previously using lower-performance MCUs, offering enhanced computational density and advanced peripheral integration within a compact footprint.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified substitutes. Ensure any replacement maintains dual-core architecture and compatible pinout if board space is constrained.
