Overview
The ST25DV16KC-IE6S3 is a dynamic NFC/RFID tag IC produced by STMicroelectronics. This device offers 16 Kbit of electrically erasable programmable memory (EEPROM) and features two interfaces: an I²C serial link and an RF link. The I²C interface can be operated from a DC power supply, while the RF link is activated when the device acts as a contactless memory powered by the received carrier electromagnetic wave. This dual-interface capability allows for fast data transfer between the contact and contactless worlds, making it versatile for various applications.
