Procurement Notes

Verify the specific suffix 'MUR' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the component meets RoHS compliance standards applicable to your manufacturing region. Ensure compatibility with the 48-QFN footprint dimensions during PCB layout finalization. Cross-reference the latest datasheet revision to validate pinout assignments before production.

Selection Notes

Select this model when a balance between processing performance and power consumption is critical for the application. The inclusion of an internal oscillator reduces external component count compared to devices requiring crystal oscillators. Consider the 1.62V minimum supply voltage for battery-operated designs where energy efficiency is paramount over high-speed switching requirements.
