Description

The DS2433-Z01 is identical to the standard DS2433 with the exception that the write cycle endurance specification is relaxed to 10,000 cycles as specified in Table 1. The device consists of a factory-lasered registration number that 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.
