ST25DV04K-JFR6D3

ST25DV04K-JFR6D3 is a dynamic NFC/RFID tag IC with 4Kb EEPROM (electrically erasable programmable memory) and fast transfer mode capability. It features 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. The ST25DV04K 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 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.
