MFRC-522 RFID Reader Kit

This is RFID Reader/Writer RC522 SPI S50 CARD AND KEYCHAIN which works on non-contact 13.56mhz communication, is designed by NXP as low power consumption, low cost, and compact size read and write chip, and is the best choice in the development of smart meters and portable hand-held devices.

It uses an advanced modulation system, fully integrated at 13.56MHz with positive non-contact communication protocols. It supports a 14443A-compatible answer signal. The DSP deals with ISO14443A frames and error correction.

This module can fit directly in handheld devices for mass production. The module uses a 3.3V power supply and can communicate directly with any CPU board by connecting through the SPI protocol, which ensures reliable work, and good reading distance.

Features :

1. Highly integrated analog circuitry to demodulate and decode responses.
2. Supports ISO/IEC 14443 A/MIFARE.
3. The typical operating distance in reading/Write mode is up to 50 mm.
4. Supports ISO/IEC 14443 A higher transfer speed communication up to 848 kBd.
5. SPI up to 10 Mbit/s.
6. FIFO buffer handles 64 bytes send and receive.
7. Flexible interrupt modes.
8. Power-down by software mode.
9. Programmable Timer.
10. 2.5 V to 3.3 V power supply.
11. CRC coprocessor.
12. Internal self-test.
