Procurement Notes

Verify the specific suffix EA against official Microchip documentation to confirm pinout compatibility and package dimensions. Ensure the procurement channel provides genuine components with traceable lot codes. Check for recent Product Change Notifications regarding marking or packaging updates. Confirm RoHS compliance status matches project requirements. Validate that the supplier offers adequate technical support for the SAM4C family.

Selection Notes

Select this component when dual-core processing isolation between application and security layers is required. The 2MB flash capacity suits complex firmware applications without external memory expansion. Consider the 144-pin LQFP package for sufficient I/O density in space-constrained designs. Evaluate power consumption profiles against the 1.62V minimum supply requirement for battery-operated scenarios.

Part Context

This part belongs to the SAM4C series of 32-bit microcontrollers based on the ARM Cortex-M4 core. It is designed for smart energy and industrial applications requiring robust security features. The series distinguishes itself through its dual-core configuration, allowing separate execution environments for different system functions within a single silicon die.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified substitutes. Ensure any replacement maintains the dual-core architecture and compatible package footprint. Verify that alternative parts meet the same electrical specifications and security certifications.
