Descriptions:

The DS2431Q+T&R is a 1-Wire EEPROM designed for small data storage applications. It provides nonvolatile memory with a unique, factory-lasered 64-bit ROM ID for secure identification. The 1-Wire interface minimizes wiring, making it suitable for space-constrained designs.

Features:

  • 1024-bit EEPROM organized into four 256-bit pages
  • 1-Wire communication reduces interconnect complexity
  • Unique 64-bit serial number ensures traceability
  • Programmable write protection for memory blocks
  • Low-power operation ideal for battery-powered devices
  • High-speed Overdrive mode for faster data transfer

This device is commonly used in asset tracking, calibration storage, and secure data logging applications.

(Note: "T&R" indicates tape and reel packaging for automated assembly.)
