[Introduction to RC522 chip]
MF RC522 is a highly integrated read-write card chip used in 13.56MHz contactless communication. It is a low-voltage, low-cost, small-sized contactless read-write card chip launched by NXP for “three-meter” applications. It is a good choice for the research and development of smart instruments and portable handheld devices. MF RC522 utilizes advanced modulation and demodulation concepts to fully integrate all types of passive contactless communication methods and protocols at 13.56MHz. Supports 14443A compatible transponder signals. The digital part handles ISO14443A frames and error detection. In addition, it also supports the fast CRYPTO1 encryption algorithm to verify MIFARE series products. MFRC522 supports the higher-speed contactless communication of the MIFARE series, with a two-way data transmission rate of up to 424kbit/s. As a new member of the 13.56MHz highly integrated read-write card series chip family, MF RC522 has many similarities with MF RC500 and MF RC530, but also has many features and differences. The communication between it and the host adopts SPI mode, which is beneficial to reducing connections, reducing the size of the PCB board, and reducing costs.
[Introduction to RFID module]
The MF522-AN module uses Philips MFRC522 original chip to design the card reading circuit. It is easy to use and low in cost. It is suitable for users with advanced applications such as equipment development and card reader development, and users who need to design/produce radio frequency card terminals. This module can be directly installed into various card reader molds. The voltage of the module is 3.3V, and it can directly connect and communicate with any user’s CPU motherboard through a few simple lines of the SPI interface, which ensures that the module works stably and reliably, and the card reading distance is long;
