Operation of a Single vs Multiple BQF00XX Devices

Design Considerations:

  • BQF family of devices enable authentication for disposable identification-sensitive use-cases.
  • 64-bit one-time programmable (OTP) ID can be used as storage for calibration data, date, or security-related information.
  • Very little standby power is required for data integrity.
  • Multiple pages allow different programming schema for different use-cases.
  • Multi-modal function for reading, writing, searching, matching data to page bank.
  • High-speed, overdrive mode is available for faster data transfer.
  • Multiple devices can be used at the same time for extended functionality.
  • Need more assistance? Ask our engineers a question at TI E2E™ design support forums.


  • Identification and lot tracing for inventory management
  • Calibration data for medical or testing instrumentation
  • Validation data for assenting device operation
  • Security keys for information-sensitive systems
