[Introduction to RC522 chip]
MF RC522 is a highly integrated reader/writer chip used in 13.56MHz non-contact communication. It is a low-voltage, low-cost, and small non-contact reader/writer chip for "three meters" applications. It is a smart meter And a better choice for the development of portable handheld devices. MF RC522 utilizes advanced modulation and demodulation concepts, and fully integrates all types of passive non-contact communication methods and protocols under 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 high-integration card reader/writer 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 reduce the connection, reduce the size of the PCB board, and reduce the cost.
[Introduction to RFID Module]
The MF522-MINI module uses the RC522 chip to design the card reading circuit. The module works at 13.56MHz frequency, conforms to the ISO14443A standard, and can support Mifare1 S50, Mifare1 S70, Mifare Light, Mifare UltraLight, and Mifare Pro. 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 CPU motherboard of the user through a few simple lines of the SPI interface, which can ensure the stable and reliable operation of the module and the long distance of the card reading, the module is easy to use, highly reliable, and small in size. And other features, can help customers to apply contactless cards to the system conveniently and quickly.
