The DS1990A serial number iButton
carrier that serves as an electronic registration number
for automatic identification. Data is transferred serially
through the 1-Wire
gle data lead and a ground return. Every DS1990A is
factory lasered with a guaranteed unique 64-bit regis-
tration number that allows for absolute traceability. The
durable stainless-steel iButton package is highly resis-
tant to environmental hazards such as dirt, moisture,
and shock. Its compact coin-shaped profile is self-
aligning with mating receptacles, allowing the DS1990A
to be used easily by human operators. Accessories
enable the DS1990A iButton to be mounted on almost
any object, including containers, pallets, and bags.

... Figure 3. 1-Wire CRC Generator 4 _______________________________________________________________________________________ The 1-Wire bus is a system that has a single bus master and one or more slaves. In all instances, the DS1990A is a slave device. The bus master is typically a micro- controller or PC. For small configurations, the 1-Wire communication signals can be generated under soft- ware control using a single port pin ...

... The initialization sequence consists of a reset pulse transmitted by the bus master followed by presence pulse(s) transmitted by the slave(s). The presence pulse lets the bus master know that the DS1990A is on the bus and is ready to operate. For more details, see the 1-Wire Signaling section. V PUP ...
