MF RC522 SPI Write/Read Module for Arduino, RS232/485 Interface
Specifications
RC522 chip Introduction
MF RC522 is applied to 13.56MHz contactless communication highly
integrated chip card reader, is for the "Three Tables" application
launch of a low-voltage, low-cost, small size and non-contact card
reader chip, smart instrumentation and portable handheld devices
developed better choice. MF RC522 using advanced modulation and
demodulation concept completely integrated in all types of 13.56MHz
passive contactless communication methods and protocols. Support
14443A compatible transponder signals. The digital part handles
ISO14443A framing and error detection. In addition, support fast
CRYPTO1 encryption algorithms, terminology validation products.
MFRC522 supports Series higher speed non-contact communication,
two-way data transfer rates up to 424kbit / s. As a highly
integrated 13.56MHz card reader new family of chips, MF RC522 MF
RC500 and MF RC530 and there are many similarities, but also have
many features and differences. It is between the host communication
using SPI mode, helps to reduce connection, reduce PCB board size
and cost.
RFID module Introduction
MF522-AN module adopts MFRC522 original reader circuit chip design,
easy to use, low cost, suitable for equipment development,
development of advanced applications such reader users, the need
for RF card terminal design / production of the user. This module
can be loaded directly into a variety of readers molds. Module uses
voltage of 3.3V, through the SPI interface simple few lines can be
directly connected to the user any CPU board communication module
can guarantee stable and reliable work, reader distance;
