DS2433T-Z01

4kbit 1-Wire EEPROM

Dallas Semiconductor -> Maxim Integrated 

DS2433-Z01

includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit Family Code (23h) plus 4096 bits of

user-programmable EEPROM.

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
