Overview
The ST25DV16K-IER6T3 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: a two-wire I2C serial link and an RF link based on ISO/IEC 15693 and NFC Forum Type 5 standards. The I2C interface can be operated from a DC power supply, while the RF interface is activated by the received carrier electromagnetic wave, enabling contactless memory access. This dual-interface capability makes the ST25DV16K-IER6T3 versatile for various applications requiring both wired and wireless data exchange.
