Table Legend:

  • DNC (Do Not Connect): This pin should be left unconnected on the PCB.
  • NC (No Connect): This pin does not have any internal connection to the device. Any component connected to this pin will not affect device performance.
  • GND_ESC (Ground Escape): Optional ground escape pins for simplifying layout. The can be connected directly to ground or left unconnected.
