Rc522 chip profile:

Mf rc522 is a high-integration card reader chip used in 13.56 mhz non-contact communication,A low voltage for three-meter applications introduced bynxp、Low cost、Small, non-contact type read-write card chip,It is a good choice for intelligent instrument and portable handheld device development. Mf rc 522 fully integrates all types of passive non-contact modes and protocols under 13.56 mhz using advanced modulation and demodulation concepts.Support 1443a compatible transponder signal.The digital part deals with iso 14443a frames and error detection.In addition, fast crypto 1 encryption algorithm is supported, and the mifare series is validated by terms. Mfrc 522 supports the mifare series of more high-speed non-contact communication, with two-way data transmission rates as high as 424kbit/s.As a new member of the 13.56 mhz high-integration read and write card series chip family, mf rc522 has many similarities, characteristics and differences with mf rc500 and mf rc530.It uses spi mode to reduce connection, reduce pcb size and reduce cost.

Introduction to rfid module:
Mf522-an module uses philips mfrc 522 original chip to design card reader circuits, which are easy to use, inexpensive, suitable for advanced applications such as equipment development, card reader development, and users who need to design/produce radio frequency card terminals.This module can be loaded directly into various card reader molds.The module uses a voltage of 3.3 v, which can be communicated directly to any cpu board of the user through simple lines of spi interface, which can guarantee the stable and reliable operation of the module and the distance of the card reader
