What the ST25DV family does
The ST25DV04KC, ST25DV16KC, and ST25DV64KC are dynamic NFC/RFID tag ICs featuring 4-Kbit, 16-Kbit, or 64-Kbit EEPROM. These devices operate on a single supply voltage of 1.8 V to 5.5 V and support a 1 MHz I²C protocol. They offer a custom fast read access up to 53 kbit/s and data retention of 40 years. The family supports ISO/IEC 15693 and NFC Forum Type 5 standards, enabling contactless memory access. Users typically employ these parts for secure data storage in contactless applications, utilizing configurable memory areas protected by passwords. The integrated fast transfer mode facilitates rapid data exchange between the RF and I²C interfaces, while an energy harvesting feature allows powering external components under specific conditions.
