【Introduction of RC522 chip】

MF RC522 is a highly integrated read-write card chip used in 13.56MHz non-contact communication. It is the 1 low-voltage, low-cost, small-volume non-contact read-write card chip launched by the company for the "three meters" application. It is a better choice for the research and development of smart meters and portable handheld devices. The MF RC522 utilizes advanced modulation and demodulation concepts and fully integrates all types of passive contactless communication methods and protocols at 13.56MHz. Supports 14443A compatible transponder signals. The digital section handles ISO14443A frames and error detection. In addition, it also supports fast CRYPTO1 encryption algorithms and word verification MIFARE series products. The MFRC522 supports the higher-speed contactless communication of the MIFARE series, with a two-way data transfer rate of up to 424kbit/s. As a new member of the 13.56MHz high-integration card family, MF RC522 has many similarities with MF RC500 and MF RC530, as well as many characteristics and differences. It uses SPI mode to communicate with the host, which is beneficial to reduce the connection, reduce the size of the PCB board and reduce the cost.

【RFID Module Introduction】

MF522-AN module uses Philips MFRC522 original chip design card reading circuit, easy to use, low cost, suitable for equipment development, card reader development and other advanced applications of users, the need for RF card terminal design/production of users. This module can be directly loaded into a variety of card reader die. The module adopts a voltage of 3.3V, and can be directly connected and communicated with any CPU motherboard of the user through a few simple lines of SPI interface, thus ensuring stable and reliable operation of the module and long card reading distance;
