<h1>Dallas/Maxim 1-Wire/iButton devices</h1>
<p>Onewire is a simple, low-cost bus system working with hundreds of devices on an up to 300m long one-wire (plus GND) bus system. It is relative slow (~16kBaud) but electrically undemanding, too. The onewire is hotplug-capable, if the host software supports it. The bus can be controlled by a single μC port pin or by special host adapter chips, which are available for RS232, Parallel, I<sup>2</sup>C, and USB to onewire conversion. They are available as ready-to-run host adapter devices, too.</p>
<p>The chips on the bus can be powered through the bus line, this is called "parasite power". All neccesary circuit and capacities for parasite power are on chip. Some chips need an additional power source to provide all features.</p>
<p>iButton is an application for onewire devices, using special packaged onewire devices as keys or for data storage. All onewire chips have a unique serial number for technical reasons, and together with the hot-plug capability this makes them useable as unique keys. In addition, many onewire chips have additional memory (EPROM, EEPROM, RAM) on the chip, which can be used to store cryptographic keys. iButtons come in various packages which are protected against corrosive agents and weather influences.</p>
