Brief introduction to RC522 Chip
The MFRC522 is a highly integrated reader/writer IC for contactless communication at 13.56 MHz. This contactless reader/writer IC is of low-cost, low voltage and small-size and is designed for the application of water meter, electricity meter and gas meter. It’s a good choice for intelligent instrument and portable device development. MF RC522 adopts advanced modulation and demodulation theory and has integrated all types of passive contactless communication mode and protocols at 13.56 MHz. It supports compatible 14443A transponder signal. The digital part deals with ISO14443A frame and error inspection. It also supports CRYPT01 encryption algorithm for verify MIFARE products. MFRC522 supports faster contactless communication such as MIFARE. The bidirectional data transfer rate is as high as 424kbit/s. As a new member in 13.56 MHz highly integrated reader/writer IC, MF RC522 bears many similarities with MF RC500 AND MF RC530 as well as different features. MF RC522 adopts SPI mode for communication with host machine, which helps to simplify wiring and downsize PCB board, thus reducing product cost.
Brief introduction to RFID module:
MF522-AN module adopts original Philips MFRC522 IC for reader circuit designation. It target client are those engaged in device development, reader development, RF card designation/production. This module can be inserted directly into various readers, which is very convenient to use and cost-effective. The module adopts 3V voltage and can be connected to any CPU motherboard through several lines in SPI interface, ensuring normal operation of the module and a long card-read distance.
