Overview
The ST25DV04K-JFR6D3, produced by STMicroelectronics, is a dynamic NFC/RFID tag IC that offers 4 Kbit of electrically erasable programmable memory (EEPROM). This device is part of the ST25DVxxx family, which includes versions with 4, 16, and 64 Kbit of EEPROM. The ST25DV04K features two primary interfaces: an I2C serial link and an RF link, enabling both wired and contactless communication. The I2C interface operates from a DC power supply, while the RF interface is powered by the received carrier electromagnetic wave, adhering to ISO/IEC 15693 and NFC Forum Type 5 standards.
