RFID, RF access and monitoring ICs has been widely used in many industries due its convenience and low cost. ST25DV64K-JFR8D3 is one of the RFID, RF access and monitoring ICs that has gained tremendous popularity in recent years. This article will provide an overview of the application fields and working principle of the ST25DV64K-JFR8D3.

The ST25DV64K-JFR8D3 chip is a secure non-contact RFID integrated in the vicinity of an inductive loop. It has an integrated analog front end (AFE) and digital system-on-chip (SOC) components for efficient communication. It can be used for identification and can provide data access information and other information for security, tracking, and access control. It can also be used in asset tracking, medical drug and supply tracking, and other areas where data retrieval, control, and access are critical.

The ST25DV64K-JFR8D3 is equipped with dual-function ICs: the ST25DV64K is the analog transceiver, while the JFR8D3 is the digital core. The ST25DV64K transceiver is composed of an RF front-end controller and an embedded low frequency (LF) embedded controller. The RF front-end controller provides wireless communication in the vicinity of the inductive loop. The embedded LF controller manages the circuit, including the digital signal processing used to decode and encode the data for transmission and reception. Additionally, the ST25DV64K includes a secure on-chip Dynamic NFC (Near Field Communication) tag that stores authentication data and enables secure access.

The JFR8D3 digital core is a high-performance 32-bit MCU family that operates up to 16 MIPS. It performs tasks such as digital signal processing, cryptographic operations, communications, and general-purpose computations. The JFR8D3 MCU also integrates several peripherals such as a real-time clock, GPIO ports, UART ports, I2C ports, and an encryption engine. The integrated peripherals enable the JFR8D3 to perform more complex tasks in the application.

The combination of the ST25DV64K transceiver and the JFR8D3 core makes the ST25DV64K-JFR8D3 a powerful and efficient IC. The integrated NFC tag ensures a secure access to the data stored in the IC. The RF front-end of the ST25DV64K is designed to operate in the inductive loop of the reader and it can communicate with readers running on the ISO/IEC 14443A and 14443B standards. The IC can also communicate with readers running on other proprietary standards. The JFR8D3 digital core is capable of performing tasks such as data encoding and decoding, cryptographic operations, and communications.

The ST25DV64K-JFR8D3 can be used in a variety of applications, including security, asset tracking, and access control. In security applications, the tag can be used to securely and remotely control or access electronic devices or access card readers. In asset tracking, the tag can be used to store and process tracking data such as location, time and date of arrival or departure, and other related information. Additionally, the IC can be used for access control applications, where it is used to enable secure access to a particular area, such as a building, a room, or a gate.

The ST25DV64K-JFR8D3 is an efficient, low-cost RFID, RF access and monitoring IC that has gained tremendous popularity in recent years due to its security features and convenience. The integrated analog and digital components of the ST25DV64K-JFR8D3 make it a suitable choice for a variety of applications such as security, asset tracking, and access control. Additionally, the secure on-chip NFC tag ensures a secure access to the data stored in the IC, making it a reliable and secure IC for secure applications.
