UFDFPN8 13.56MHz ISO15693 4Kbit Description

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.

ST25DVxxx offers a fast transfer mode between the RF and contact worlds, thanks to a 256 bytes volatile buffer (also called Mailbox).

In addition, the GPO pin of the ST25DVxxx 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.
