MFRC52201HN1,118

The MFRC52201HN1 is a readily available, small-sized IC from NXP Semiconductors. It is a contactless reader, which can be used to read or detect the presence of RFID tags within its vicinity. The core of its technology lies in its use of an on-board microcontroller and an internal antenna to interact with and store data from external passive RFID tags.

RFID

The MFRC52201HN1 is classified as an RFID (Radio Frequency Identification) reader, or otherwise known as contactless ID system. A contactless ID system is a type of electronic identification platform that uses RFID technology to capture, store, and transfer secure data. The main focus of RFID is to collect and interact with data related to objects within a designated area. In the case of the MFRC52201HN1, this is achieved by collecting the data encoded in a tag and communicating it to a backend system for further processing.

RF Access

The MFRC52201HN1 makes use of radio frequencies (RF) to access and interact with nearby RFID tags that contain secure data. This is done by briefly pulsing a radio transmission over the required frequency and then collecting and storing the information sent back from the tag. These frequencies can range anywhere from 125 KHz to 5.8 GHz, depending on the application. The received data is then further processed and acted upon, depending on its content.

Monitoring ICs

The MFRC52201HN1 can also be used as a monitoring IC for various applications. By using a combination of the on-board microcontroller and external sensors, the IC is able to measure and process data from the environment. This could include anything from air temperature, humidity, voltage and current readings, GPS coordinates, motion detectors, etc. This data can then be transferred from the IC to the backend system for further processing and analysis.

Application Field and Working Principle

The MFRC52201HN1 can be used in a variety of applications, ranging from access control and authentication systems, to monitoring or inventory management. In the case of access control systems, the IC can be used to grant permission in an engaging and secure way, by reading the data stored in a tag and sending it to a backend system for authorization. Similarly, for inventory or asset management, the IC can be used to collect and store data from tags about a tracked object. This can help with real-time tracking of objects and their respective associated data.

The working principle of the MFRC52201HN1 is simple. The IC is equipped with an onboard microcontroller and a built-in antenna. This antenna emits multiple radiation pulses in order to detect the presence of nearby RFID tags. When a tag is within its vicinity, it actively interacts with the tag and collects its data. This data is then transmitted to a backend system for verification, authorisation or further processing.
