Working Principle

This multipurpose RFID chip contains various components and circuitry but the working principle behind it is the same. The ST25R3913-BQFT contains several main components such as the integrated RF transceiver, baseband controller, modem, NFC interface and STM32ARM processor. The antenna is the main component of the reader and transmits and receives radio signals from the tag. The antenna sends the received signals to the RF transceiver which in turn deletes the noise and converts the signals into digital signals.

The baseband controller then processes the digital data received by the RF transceiver. It controls the data link and is responsible for implementing the protocol logic. The modem then controls the modulation and demodulation process and is responsible for sending and receiving data. The NFC interface is responsible for regulating the communication between the reader and the tag and also encrypts the data.

The STM32ARM processor is responsible for controlling the operation of the IC. It reads the data received by the baseband controller, processes it, and sends commands and data to the controller. Finally, the ST25R3913-BQFT also contains a number of security features that enhance data security and prevent malicious attacks.

Conclusion

Ultimately, the ST25R3913-BQFT provides comprehensive RFID and RF access support, exceptional performance and power consumption and advanced security features. The range of applications for this IC is expanding due to its versatility and many features, making it a great choice for implementing automation solutions, access control solutions and other applications where secure communication is required.
