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.
Applications:
- 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
