ST25DV16KC-JF8D3

ST25DV16KC-JF8D3 is a dynamic NFC/RFID tag IC with fast transfer mode capability and optimized I2C offering 16Kbit of electrically erasable programmable memory (EEPROM). It offers 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 device acts as a contactless memory powered by the received carrier electromagnetic wave. In I²C mode, this device's user memories contain up to 512bytes, 2048bytes, and 8192bytes, which could be split into 4 flexible and protectable areas. It offers 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 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.
