rc522 datasheet

The RC522 is a highly integrated contactless reader/writer IC for handling communication between a variety of contactless communication protocols. It features a 13.56 MHz RFID reader that supports ISO14443 Type A and B standards, as well as MIFARE and FeliCa communication protocols. With its embedded communication modules, the RC522 can effectively read and write data to RFID cards and tags for various applications, including access control, time attendance, ticketing, and payment systems. The RC522 IC is equipped with a 40-bit unique identifier (UID) and supports a variety of data transmission rates up to 424 kbps. Its on-chip voltage regulator allows for easy integration into different designs, and its low power consumption makes it suitable for battery-operated devices. With its SPI communication interface, the RC522 can be easily connected to microcontrollers and other host systems. The RC522 is an ideal solution for developers and designers looking to implement contactless communication in their products.
