MF RC522 is a high-integration read/write card chip used in 13.56MHz contactless communication. It is a low-voltage, low-cost, small-sized contactless card reader chip introduced by NXP for “three-table” applications. It is a good choice for the 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 13.56 MHz. Supports 14443A compatible transponder signals. The digital part handles ISO14443A frame and error detection. In addition, it supports the fast CRYPTO1 encryption algorithm and verifies the MIFARE series of products. The MFRC522 supports the MIFARE series of higher speed contactless communication with bidirectional data rates up to 424 kbit/s. As a new member of the 13.56MHz high-integration read-write card family, the MF RC522 has many similarities with the MF RC500 and MF RC530, as well as many features and differences. It uses SPI mode for communication with the host, which helps to reduce wiring, reduce PCB board size and reduce cost.
