• Provides robust connectivity through an integrated MAC and PHY supporting Ethernet communication standards.
• Includes multiple peripheral controllers such as DMA, PWM, and watchdog timers for efficient system management.
• Features flexible I/O configurations with up to 117 accessible pins for diverse interface requirements.

Applications

• Industrial automation systems requiring real-time control and Ethernet connectivity
• Smart energy metering devices utilizing high-resolution analog-to-digital conversion
• Consumer electronics with embedded USB and display interface capabilities

Procurement Notes

Verify the specific suffix 'CU' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the LFBGA-144 package. Confirm that the required firmware framework supports the SAM4E series architecture before procurement.

Selection Notes

Select this component when a balance of processing power and connectivity is required. The 120MHz speed suits complex algorithm execution. The 1MB Flash allows for substantial application code storage. Consider the 144-pin package size relative to board space constraints compared to smaller variants in the SAM4E family.

Part Context

This part belongs to the SAM4E series, designed for applications needing high performance and rich connectivity. It shares the Cortex-M4 core with other SAM4 series members but distinguishes itself with specific memory sizes and peripheral sets tailored for industrial and consumer markets.

Replacement Considerations

Consult Microchip documentation for direct pin-compatible or functionally equivalent alternatives within the SAM4E or SAM4S families. Verify memory capacity and package dimensions match before substitution.
