Product overview
Description
The ST25DV04KC, ST25DV16KC and ST25DV64KC devices are NFC RFID tags offering respectively 4‑Kbit, 16‑Kbit, and 64‑Kbit of electrically erasable programmable memory (EEPROM). The ST25DV04KC, ST25DV16KC and ST25DV64KC offer two interfaces. The first one is an I2C serial link and can be operated from a DC power supply. The second one is an RF link activated when the ST25DV04KC, ST25DV16KC and ST25DV64KC act as a contactless memory powered by the received carrier electromagnetic wave. In I2C mode, the ST25DV04KC, ST25DV16KC and ST25DV64KC user memories contain up to 512 bytes, 2048 bytes and 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, the ST25DV04KC, ST25DV16KC and ST25DV64KC user memory contains respectively up to 128 blocks, 512 blocks and 2048 blocks of 4 bytes which could be split in 4 flexible and protectable areas.
The ST25DV04KC, ST25DV16KC and ST25DV64KC offer a fast transfer mode between the RF and contact worlds, thanks to a 256 byte volatile buffer (also called Mailbox). In addition, the GPO pin of the ST25DV04KC, ST25DV16KC and ST25DV64KC provides data informing the contact world about incoming events, like RF field detection, RF activity in progress or mailbox message availability. An energy harvesting feature is also proposed when external conditions make it possible.
Herein after all concerned devices (ST25DV04KC, ST25DV16KC and ST25DV64KC) are mentioned as ST25DVxxKC.
