Product Introduction

Introduction to RC522 Chip

MF RC522 is a highly integrated read-write card chip used in 13.56MHz non-contact communication. It is a low-voltage, low-cost, and small-sized non-contact read-write card chip launched by NXP for the "three meter" application. It is a good choice for the research and development of smart instruments and portable handheld devices. The MF RC522 utilizes advanced modulation and demodulation concepts, fully integrating all types of passive non-contact communication methods and protocols at 13.56MHz. Supports 14443A compatible responder signals. The digital part processes ISO14443A frames and error detection. In addition, it also supports fast CRYPTO1 encryption algorithm and language verification for MIFARE series products. MFRC522 supports higher speed contactless communication in the MIFARE series, with a bidirectional data transfer rate of up to 424kbit/s. As a new member of the 13.56MHz high integration read-write card series chip family, MF RC522 has many similarities with MF RC500 and MF RC530, as well as many characteristics and differences. It communicates with the host using SPI mode, which is beneficial for reducing wiring, shrinking PCB board size, and lowering costs.

Introduction to RFID Module

The MF522-AN module adopts the original Philips MFRC522 chip to design the card reading circuit, which is easy to use and cost-effective. It is suitable for users in advanced applications such as device development and card reader development, as well as users who need to design/produce RF card terminals. This module can be directly installed into various card reader molds. The module adopts a voltage of 3.3V and can be directly connected to any CPU motherboard for communication through a few simple lines of SPI interface, ensuring stable and reliable operation of the module and long card reading distance;
