The ST25DV04K-JFR6L3 is a highly integrated secure RFID IC, specifically designed for RF Access and Monitoring applications. This IC is equipped with the latest RFID technology and offers superior reliability and integration. It incorporates an innovative ISO14443A/B transponder and supports both HF and UHF bands.

The ST25DV04K-JFR6L3 is a contactless smart card IC that is excellent in terms of data exchange and secure storage. It has 16 KB of secured EEPROM memory that can store a wide variety of data, including 48 byte UIDs, 886 byte User-defined data fields, and 8KB of user-programmable access control lists. All memory areas are secured through hardware mechanisms that protect data in case of power loss, or unauthorized attempts to access data.

The ST25DV04K-JFR6L3 also provides high-performance RF communication. It supports high-speed ISO14443A/B communication, including 106 kbps bit rate with software demodulation and detection. The device also features an integrated NFC (Near Field Communication) capability allowing it to communicate with NFC enabled phones such as Android, and Blackberry. The IC supports ISO14443-2 and ISO14443-3 compliant card communication and supports the new NFC Forum Type-4 phone communication.

The ST25DV04K-JFR6L3 works on the principle of Activating RF fields. An RF field that is transmitted between a contactless card and a reader is used to transfer data between two devices. The RF field induces an electric field on the IC which is detected by the card’s receiver. The card then responds with its stored data or performs actions such as authenticating a user. A highly secure protocol and mutual authentication ensures secure communication between the card and the reader.

The ST25DV04K-JFR6L3 is ideal for applications such as access control, inventory management, authentication, secure authorization, secure payments, customer loyalty, ticketing systems, and more. These use cases require a secure chip that is compliant with industry standards. The ST25DV04K-JFR6L3 meets those needs perfectly by offering high-integration and high-security RFID technology.
