ST25DV04K-IER6S3 Datasheet PDF - ST Microelectronics

●The ST25DVxxx device is a NFC RFID Tag offering 4 Kbit, 16 Kbit, and 64 Kbit of electrically erasable programmable memory (EEPROM). ST25DVxxx offers 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 when ST25DVxxx acts as a contactless memory powered by the received carrier electromagnetic wave. - In I2C mode, the ST25DVxxx user memory contains up to 8192 bytes, which could be split in 4 flexible and protectable areas. - In RF mode, following ISO/IEC 15693 or NFC forum type 5 recommendations, ST25DVxxx user memory contains up to 2048 blocks of 4 bytes which could be split in 4 flexible and protectable areas.
