Procurement Notes
Verify the specific suffix 'AUR' against official Microchip documentation to confirm tape-and-reel packaging and automotive-grade qualification status. Ensure the order matches the exact pinout and thermal specifications of the TQFP-100 variant. Cross-reference the datasheet revision date to confirm current manufacturing status and any potential obsolescence notices before finalizing procurement.
Selection Notes
Select this component when high-performance processing combined with hardware security is required. The 120 MHz Cortex-M4 core offers sufficient speed for complex algorithms. Compare memory sizes with other SAM4C variants if larger storage is needed. Verify that the 1.62 V to 3.6 V voltage range aligns with the system power design constraints.
Part Context
This part belongs to the SAM4C family, which is designed for high-performance applications. It shares architectural similarities with other SAM4 series MCUs but offers specific memory configurations. The family emphasizes security and connectivity, making it suitable for demanding embedded environments.
Replacement Considerations
Consult Microchip's official cross-reference tools for verified substitutes. Potential alternatives may include other SAM4C variants with different memory sizes or packages. Ensure any replacement maintains compatibility with the existing firmware and hardware interface requirements.
