RC522 Module IC Card High-integration 13.56mhz Read-write Card Series for Access Control System

Features: MF RC522 is a member of the high-integration read-write card series used in 13.56MHz contactless communication. It is a low-voltage, low-cost, small-sized contactless card reader chip developed by for for the for three-table application. It is a good choice for the development of smart meters and portable handheld devices. The MF RC522 utilizes advanced modulation and demodulation concepts to fully integrate all types of passive contactless communication methods and protocols at 13.56 MHz. Support for multi-tier applications of for ISO14443A. Its internal transmitter section drives the reader antenna to communicate with the for ISO 14443A/for card and transponder, eliminating the need for additional circuitry. The receiver section provides a robust and efficient demodulation and decoding circuit for handling for ISO14443A compatible transponder signals. Digital part processing for ISO14443A frame and error detection (parity & CRC). In addition, it supports the fast CRYPTO1 encryption algorithm for validating the for family of products. The MFRC522 supports for MIFARE’s higher speed contactless communication with bidirectional data rates up to 424kbit/s. As a new member of the 13.56MHz high-integration read-write card family, the MF RC522 has many similarities with the MF RC500 and MF RC530, as well as many features and differences. It communicates with the host with less serial communication, and can choose one of for / I2C or serial UART (similar to RS232) mode according to different user requirements, which is beneficial to reduce wiring and reduce PCB board volume, cut costs. Scope of application: MF RC522 is suitable for a variety of applications based on for ISO/IEC 14443A standard and requires low-cost, small size, high performance and single-supply contact
