STMicroelectronics RF and Wireless - RFID, RF Access, Monitoring ICs ST25DV04K-IER6C3

The ST25DV04K-IER6C3 is a dynamic NFC/RFID tag integrated circuit that features 4 Kbits of EEPROM memory. It operates with a single supply voltage ranging from 1.8 to 5.5 V and supports a two-wire I²C interface with a maximum protocol speed of 1 MHz. The device complies with ISO/IEC 15693 standards and is certified as an NFC Forum Type 5 tag, enabling it to support various modulations, coding, and data rates. This IC allows for fast data transfer with a custom read access speed of up to 53 Kbit/s and supports both single and multiple block read/write operations. The memory can be accessed in blocks of 4 bytes via the RF interface, while the I²C interface allows for byte-level access. The device includes a 256-byte dedicated buffer for fast transfer mode and features energy harvesting capabilities to power external components. The ST25DV04K-IER6C3 is designed for a wide temperature range, operating from -40 to 85 °C, and can withstand up to 125 °C in certain package types. It also offers data protection through configurable memory areas secured by multiple 64-bit passwords. With a write endurance of up to 1 million cycles at 25 °C, this IC is suitable for applications requiring reliable and long-lasting memory solutions.
