Introduction to RC522 chip

MF RC522 is a highly integrated card reader/writer chip used in 13.56MHz contactless communication. It is a low-voltage, low-cost, and small-sized contactless reader/writer chip developed by NXP for the "three-meter" application. It is a better choice for the development of smart meters and portable handheld devices. MF RC522 utilizes advanced modulation and demodulation concepts, and fully integrates all types of passive non-contact communication methods and protocols at 13.56MHz. Support 14443A compatible transponder signal. The digital part handles ISO14443A frames and error detection. In addition, it also supports the fast CRYPTO1 encryption algorithm to verify the MIFARE series products. MFRC522 supports the higher-speed non-contact 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 reader/writer 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 conducive to reducing the connection, reducing the size of the PCB board and reducing the cost.

Introduction to RFID Module

MF522-AN module adopts Philips MFRC522 original chip to design the card reading circuit, which is easy to use and low in cost. It is suitable for users of 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 loaded into various card reader molds. The module adopts a voltage of 3.3V, and it can directly connect to any user's CPU motherboard through a few simple lines of the SPI interface, which can ensure the stable and reliable operation of the module and a long card reading distance.
