Procurement Notes
Verify the specific suffix 'MUR' indicates tape and reel packaging when ordering. Confirm the manufacturer designation as Microchip Technology following the acquisition of Atmel. Ensure compatibility with existing design tools and development environments supported by the SAM4L family before finalizing procurement.
Selection Notes
Select this component for designs needing a balance of processing power and energy efficiency. The inclusion of a hardware MPU supports secure application execution. Consider the available I/O count and peripheral set against system requirements. Verify that the QFN package fits the physical constraints of the target PCB layout.
Part Context
This part belongs to the SAM4L series of microcontrollers based on the ARM Cortex-M4 architecture. The series is designed for applications demanding high performance with minimal power consumption. It serves as a successor to earlier AVR-based solutions, offering enhanced computational capabilities and modern connectivity options within a compact form factor.
Replacement Considerations
Check for pin-to-pin compatible alternatives within the SAM4L family, such as variants with different memory sizes. Verify if newer generations like the SAM L21 or SAM C21 offer necessary upgrades while maintaining software compatibility.
