What do you mean a free pin? For parasite mode power comes on data pin.

Yeah, you are right, what was I thinking when I made that post?

Actually, there is a recommended parasitic configuration that uses two output pins from your CPU, one to drive a MOSFET to provide a better power supply for the single data/power wire. See Figure 6 in https://datasheets.maximintegrated.com/ ... S18B20.pdf
