ST25DV04KC-IE6S3 ST RFID, RF Access, Monitoring ICs

The ST25DV04KC-IE6S3 from STMicroelectronics is an NFC Forum Type 5 certified dynamic tag integrating a 4‑Kbit EEPROM alongside an I²C interface for direct MCU communication and a 13.56 MHz RF interface for contactless access. For selection, it operates from 1.8–5.5 V over −40 °C to +85 °C in an SO‑8 package; the 256‑byte mailbox enables fast transfer mode between the two interfaces, and the GPO interrupt pin notifies the host of RF events without polling. Energy harvesting powers external components, and an I²C‑controlled RF command interpreter adds flexibility. In application, it serves parameter setting, data logging, and calibration in consumer electronics, industrial automation, asset tracking, healthcare, home appliances, and retail, especially where battery‑free, wireless configuration or field‑service access is critical.
