Technical information

  • Technology: TSMC 55 uLP
  • Add-ons:
    • Over-voltage protection module (OPM) required for 2.7 to 5.5 V and 1.9 to 4.4 V input voltage range. The OPM enables over-voltage operation (up to 5.5 V) while using standard process 3.3 V devices. Power-On-Reset and Brown-On-Reset circuit (POR-BOR) Temperature sensor Power ON indicator
