The power to read and write the DS2433-Z01 is derived entirely from the 1-Wire
communication line.
The memory is organized as sixteen pages of 256 bits each. The scratchpad is an additional page that acts
as a buffer when writing to memory. Data is first written to the scratchpad where it may be read back for
verification. A copy scratchpad command will then transfer the data to memory. This process insures data
integrity when modifying the memory. The 64-bit registration number provides a guaranteed unique
identity which allows for absolute traceability and acts as node address if multiple DS2433-Z01 are
connected in parallel to form a local network. Data is transferred serially via the 1-Wire protocol, which
requires only a single data lead and a ground return. The PR-35 and SOIC packages provide a compact
enclosure that allows standard assembly equipment to handle the device easily for attachment to printed
circuit boards or wiring. Typical applications include storage of calibration constants, board
identification, and product revision status.
The DS2433X-Z01 flip-chip packaged option is built to the highest quality standards and manufactured
for long term reliability. All Dallas Semiconductor devices are made using the same quality materials and
manufacturing methods. However, standard versions of the DS2433X-Z01 are not exposed to
environmental stresses, such as burn-in, that some industrial applications require. For specific reliability
information on this product please contact Dallas Semiconductor.
