NFC Type 5 / RFID tag IC with 2-Kbit EEPROM, product identification and protection

ST25TV02K and ST25TV512 are NFC/RFID tag ICs with a tamper-proof feature, and specific modes to protect tag access, such as Untraceable mode.

These devices feature a digital signature used to prove the origin of the chip in cloning detection, embed a configurable EEPROM with 60-year data retention, and can be operated from a 13.56 MHz long-range RFID reader or an NFC phone.

The contactless interface is compatible with the ISO/IEC 15693 standard and NFC Forum Type 5 tag.

All features
Contactless interface
- Based on ISO/IEC 15693
- NFC Forum Type 5 tag certified by the NFC Forum
- Supports all ISO/IEC 15693 modulations, coding, subcarrier modes and data rates
- Custom Fast read access up to 53 Kbit/s
- Single and multiple block reads
- Single block writes
- Internal tuning capacitance: 23 pF, 99.7 pF
- Proprietary Inventory commands for speeding up the inventory process
- Up to 2 Kbits of EEPROM
- RF interface accesses blocks of four bytes
- Write time from RF: typical 5 ms for one block
- Data retention: 60 years
- Minimum endurance: 100 k write cycles
- 16-bit event counter with anti-tearing
Data protection
- User memory: two or three areas, read and/or write protected by two 32-bit encrypted - passwords for three areas or one 64-bit encrypted password for two areas
- System configuration: write protected by a 32-bit encrypted password
- Permanent write locks at a block level
Product identification and protection
- Kill mode and untraceable mode
- Tamper detect capability (patent pending)
- TruST25 digital signature
- EAS (electronic article surveillance) capability
Privacy protection
- Consumer privacy can be protected through the following features:
* Kill mode
* Untraceable mode
- In association with:
* Passwords with cover coding
* Data and configuration locks (permanent or temporary)
- Temperature range
From - 40 to 85 °C
- Package
* Sawn and bumped wafer, ECOPACK2 (RoHS compliant)
* 5-pin package, ECOPACK2 (RoHS compliant)
- Compatibility ST25TV02K / LRI2K
* Full compatibility in terms of functionality and capacitances with two exceptions:
1).Kill command requires option_flag to be set to 0
2).Error codes and error generation can be different on a per command basis Read less
