Procurement Notes
Verify the specific suffix 'CUR' against official Microchip documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning.
Selection Notes
Select this component when both Ethernet connectivity and USB support are required in a single MCU. The 120 MHz Cortex-M4 core provides sufficient processing power for complex protocol stacks. Verify that the 128 kB RAM meets application data handling requirements and that the 1 MB Flash capacity accommodates firmware size.
Part Context
This part belongs to the SAM4E series of Microchip's ARM-based microcontrollers. The series is designed for applications requiring robust connectivity and processing performance. It shares architectural similarities with other SAM4 variants but distinguishes itself through its specific combination of Ethernet and USB peripherals.
Replacement Considerations
Consult Microchip's official cross-reference tools for verified substitutes. Consider the ATSAM4E16JA or ATSAM4E16HA if pinout or package differences exist. Ensure functional equivalence of Ethernet and USB peripherals before substitution.
