The ST25DV04K, ST25DV16K and ST25DV64K devices are NFC RFID tags offering respectively 4 Kbit, 16 Kbit, and 64 Kbit of electrically erasable programmable memory (EEPROM). ST25DV04K, ST25DV16K and ST25DV64K offer two interfaces. The first one is an I2C serial link and can be operated from a DC power supply. The second one is a RF link activated
