RC522 RFID IC Card Sending S50 Fudan Card / Keychain
RC522 chip [Introduction] MF RC522 is applied to 13.56MHz contactless communication highly integrated chip card reader£¬ is NXP for "three table" application introduced a low-voltage£¬ low-cost£¬ small size and non-contact chip card reader£¬ is a good choice for smart meters and portable handheld devices developed. MF RC522 using advanced modulation and demodulation concept completely integrated in all types of passive 13.56MHz contactless communication methods and protocols. Support 14443A compatible transponder signal. The digital part handles ISO14443A framing and error detection. In addition£¬ support fast CRYPTO1 encryption algorithm£¬ the term verification MIFARE products. MFRC522 MIFARE family support higher speed non-contact communication£¬ two-way data transfer rates up to 424kbit / s. As a new member of the highly integrated 13.56MHz card reader series chip family£¬ MF RC522 MF RC500 and MF RC530 and there are many similarities£¬ but also have many features and differences. Between it and the host communication using SPI mode£¬ helps to reduce the connection£¬ reduce PCB board size£¬ and reduce costs. RFID module [Introduction] MF522-AN module uses Philips MFRC522 original reader circuit chip design£¬ easy to use£¬ suitable for device development£¬ advanced applications such as user reader development£¬ the need for RF card terminal design / production users. This module can be loaded directly into a variety of readers mold. Module uses voltage of 3.3V£¬ a few simple SPI interface cable can be connected directly to the motherboard CPU to communicate with any user£¬ the module can guarantee stable and reliable work£¬ reader distance.
