RC522 chip Description:
MF RC522 is used in 13.56MHz contactless communications in the highly integrated read and write card chip is NXP company for the “three tables” application introduced a low voltage, low cost, small contactless card reader chip, Is a smart instrument and a portable handheld device R & D better choice. 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 frames and error detection. In addition, support for fast CRYPTO1 encryption algorithm, language verification MIFARE series. MFRC522 supports MIFARE series of high-speed non-contact communication, bidirectional data transfer rates up to 424kbit / s. As a new member of 13.56MHz highly integrated read / write card family, MF RC522 has many similarities with MF RC500 and MF RC530, and also has many features and differences. It communicates with the host using SPI mode, will help reduce wiring, reduce the PCB board size, reduce costs.
RFID Module Introduction:
MF522-AN module uses Philips MFRC522 original chip design reader circuit, easy to use, low cost, suitable for equipment development, reader development and other advanced applications of users, the need for RF card terminal design / production users. The module can be directly loaded into a variety of card reader mold. Module voltage is 3.3V, a few lines through the SPI interface can be directly connected with any user CPU board communication, you can ensure stable and reliable module work, the reader from the far
