Description:

The ST25DV04K, ST25DV16K and ST25DV64K devices (hereinafter referred collectively to as ST25DVxxx) are

NFC RFID tags offering, respectively 4, 16, and 64 Kbit of electrically erasable programmable memory (EEPROM).

These devices feature two interfaces: the first one is an I2C serial link that can be operated from a DC power supply,

the second one is an RF link activated when the device acts as a contactless memory powered by the received carrier

electromagnetic wave. In I2C mode, the user memory contains up to 512, 2048, or 8192 bytes, which can be split in four

flexible and protectable areas. In RF mode, following ISO/IEC 15693 or NFC Forum Type 5 recommendations, the user

memory contains up to 128, 512, or 2048 blocks of 4 bytes, which can be split in four flexible and protectable areas. The

ST25DVxxx devices offer 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 provides data about incoming events, like RF field detection, RF activity

in progress, or mailbox message availability. An energy harvesting feature is also available, when external conditions make

it possible.
