The MFRC52302HN1, 157 is an application specification and working principle of one of the most popular Radio-Frequency Identification (RFID), RF Access, Monitoring Integrated Circuit (ICs), which is produced by NXP Semiconductors.

Overview

The MFRC52302HN1,157 is designed for RFID and access control applications. It is compatible with the 13.56 MHz frequency band, meaning it can be read and powered by up to 80 cm with a frequency of 13.56 MHz. Its secure authentication and encryption option prevents cloning of the tags. The versatility of the MFRC52302HN1,157 is further widened by its ability to support advanced security features, such as 2K bits memory, which can be used to store data. It is available in an ISO/IEC 15693 discrete transponder format, and it is compatible with many ISO/IEC 15693 transceivers and readers.

Benefits

Apart from the features already offered by the MFRC52302HN1,157, it includes a full suite of security features. The device is capable of protecting customer confidential information from unauthorized access and tampering, utilizing an AES 128-bit encryption module along with a key-hiding feature. Additionally, the device also has the convenience of a pre-authorized entry list, which allows customers to enter information about people who have been granted access to the property, and the MFRC52302HN1, 157 will compare it against the list of pre-authorized entries before allowing access. Furthermore, the use of this device also provides a tamper detection feature, which will alert personnel if any abnormalities are detected on the property.

Applications

The most commonly used application for the MFRC52302HN1,157 is in security applications. It is mainly used for access control systems, allowing entry to authorized personnel or even providing vehicle entry and exit points. It is particularly useful for controlling the entrance to restricted areas, such as government facilities and military bases. Additionally, it can also be used in building security systems, as the encrypted data stored in the device helps to ensure that only the right person can gain access.

Working Principle

The working principle of the MFRC52302HN1,157 is fairly simple. It uses the 13.56 MHz frequency and a Digital Signal Processor (DSP) to send and receive data in the form of radio signals. When a user tries to gain access to a secure area, the reader device used recognizes the data stored in the RFID card by scanning the card. Once the card is authenticated, the information is passed on to the database, which then determines if the user has been entered into the database as an authorized personnel or not. If the authentication is successful, the controller grants access for the user.

The power source for the MFRC52302HN1,157 is composed of both an integrated battery and a solar cell that receives power from the reader device. The device uses the power to send and receive data to and from the reader device. The data is then stored into the identifying memory of the device, which can be read if needed.

Conclusion

In conclusion, the MFRC52302HN1,157 is an RFID, RF Access, Monitoring IC which is designed to be used in security applications, mainly for access control. It is compatible with the 13.56 MHz frequency band, ensuring the safety of sensitive data with its AES 128-bit encryption and key-hiding features. Additionally, it also supports pre-authorized entry list and tamper detection, ensuring the security of restricted areas.
