Description

The DS2431X is a 1-Kb EEPROM chip organized as one page of 32 bytes, with an additional 64-bit registration number that acts as its unique identity for traceability and control on a 1-Wire network. Data is transferred serially through the 1-Wire protocol, which requires only a single data lead and a ground return for communication.

Applications:

  • Battery pack identification
  • Medical sensor calibration data storage
  • Electronic cash handles
  • Access control

Features:

  • 1024 bits of EEPROM memory organized as one page of 32 bytes
  • Page write cycle time: 5ms (typical)
  • Write cycle endurance of 500,000 cycles (minimum)
  • Data retention of 10 years (minimum)
  • Unique, factory-lasered and tested 64-bit registration number (8-bit family code + 48-bit serial number + 8-bit CRC tester) assures absolute traceability
  • Built-in multidrop controller for single-point control of multiple devices
  • Communicates to host with a single digital signal at 14.2kbps using 1-Wire protocol
  • Operating temperature range of -40°C to +85°C

Benefits:

  • Offers flexible and reliable nonvolatile memory for various applications.
  • Provides a cost-effective solution for storing configuration and calibration data.
  • Simplifies system design with its single-wire communication interface.
  • Ensures data integrity with its built-in error detection and correction features.

The DS2431X's EEPROM memory can be used to store configuration, calibration, or other critical information. The unique 64-bit registration number allows for individual identification and tracking of devices on a 1-Wire network. The device derives its power from the 1-Wire communication line, eliminating the need for an external power supply.
