ST25DV04K-IER6C3

ST25DV04K-IER6C3 is a dynamic NFC/RFID tag IC with 4Kbit EEPROM, and fast transfer mode capability. This device 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. It offers a fast transfer mode between the RF and contact worlds, thanks to a 256bytes 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.
