Procurement Notes

Verify the specific suffix 'AU' confirms the LQFP-100 package and industrial temperature range during procurement. Confirm RoHS compliance status as indicated in official documentation. Ensure compatibility with existing board layouts due to the specific pinout configuration. Cross-reference the manufacturer part number directly with Microchip Technology to avoid counterfeit components.

Selection Notes

Select this component when a dual-core ARM Cortex-M4 solution is required for separating application logic from security functions. It is suitable for designs needing substantial program storage and RAM within a 100-pin form factor. Consider the 120 MHz speed and extensive I/O count for complex peripheral integration. Evaluate power consumption requirements against the 1.32 V to 3.6 V operating range.

Part Context

This device belongs to the SAM4C family of 32-bit microcontrollers designed for smart energy and industrial markets. It builds upon the Cortex-M4 core with added security features and dual-core capabilities. The family emphasizes system-level integration for secure data handling and high-speed processing in constrained environments.

Replacement Considerations

ATSAM4C32EA-AU: Offers identical specifications but utilizes a 144-LQFP package instead of LQFP-100.
