【Introduction to RC522 chip】

MF RC522 is a read-write card chip that is used in 13.56MHz non-contact communication. It is an NXP company targeted“Three Tables” A low-voltage, low-cost, and small non-contact read-write card chip launched by the application is a better choice for the development of smart instruments and portable handheld devices. MF RC522 uses advanced concepts of modulation and demodulation, which fully integrates passive non-contact communication methods and protocols of all types of passive non-contact communication in 13.56MHz.Support 14443A compatible answers signal. The digital part handles the ISO14443A frame and error detection. In addition, it also supports the fast Crypto1 encryption algorithm and verification of MiFare series products.MFRC522 supports non-contact communication with higher-speed MiFare series, and the two-way data transmission rate is as high as 424kbit/s.As a new member of the 13.56MHz high integration read and write card series chip family, MF RC522 has many similarities with MF RC500 and MF RC530 and also has many characteristics and differences. It adopts the SPI mode in the communication between the host, which is conducive to reducing the connection, reducing the volume of PCB boards, and reducing costs.

【Introduction to the RFID module】

The MF522 -N module uses Philips MFRC522 original chip design card reading circuit. It is easy to use and low cost. It is suitable for users with high-end applications such as device development and card reader development, and users who need radio frequency card terminal design/production. This module can be directly loaded with various card reader molds. The module adopts a voltage of 3.3V. A few lines with a simple line with the SPI interface can be connected directly to the user’s CPU motherboard. It can ensure that the module is stable and reliable.
