PSoC Designer for PSoC1 has a 1-Wire component which can be used to interface with 1-Wire devices such as iButtons.
PSoC Creator for PSoC 3/5/5LP Does not have a 1-Wire component.
Interfacing to a 1-Wire device is so simple that maybe it's just not worth creating a whole compeont for.
On my blog site I have written up what is required to detect, read from and write to a 1-Wire device. The project is based around the CY8CKIT-050 but is easily portable to just about any device or dev kit.
The main article is here.
The complete project is attached to this post.

Let me add a couple of projects:
I had a PSoC5 project for one sensor DS18b20.
In the new project for PSoC4 added search sensors (preferably no more than 8 )and color display.
I hope this is useful for someone. TFT240x320_ThempLogger.zip

Hi Bob
I've been pretty quiet on PSoC for a while now, but I do like to tinker with it from time to time.

Hi Dana
Thanks for adding the Maxim data sheet.
One thing my project won't do is detect and communicate when there are more than one 1-wire devices on the wire.
It should not be too hard to add that to the project, and I will leave that as an exercise for the reader!
