STMicroelectronics RFID, RF Access, Monitoring ICs ST25DV04K-JFR6U3

The ST25DV04K-JFR6U3 is a dynamic NFC/RFID tag IC that operates at 13.56 MHz and complies with ISO/IEC 15693 standards. It features 4 Kbits of EEPROM memory and supports a two-wire I²C interface with a maximum clock speed of 1 MHz. The device can operate with a single supply voltage ranging from 1.8 to 5.5 V. This IC is designed for contactless communication and can achieve fast data transfer rates of up to 53 Kbit/s. It allows for multiple byte programming, with a write time of approximately 5 ms for both I²C and RF modes. The memory can be organized into flexible and protectable areas, with data retention of up to 40 years and endurance of 1 million write cycles at 25 °C. The ST25DV04K includes features such as a half-duplex 256-byte dedicated buffer for fast transfer between I²C and RF interfaces, an energy harvesting capability, and a configurable GPO pin for event notifications. It operates within a temperature range of -40 to 85 °C, with certain packages supporting up to 125 °C. The device is available in various package types, including SO8, TSSOP8, UFDFPN8, and WLCSP10, and is RoHS compliant.
