Description

The device is a highly integrated reader / writer IC for contactless communication at 13.56 MHz. The reader supports ISO/IEC 14443 A/MIFARE mode.

The MFRC522 internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443 A/MIFARE cards and transponders without additional active circuitry. The receiver module provides a robust and efficient implementation for demodulating and decoding signals from ISO/IEC 14443 A/MIFARE compatible cards and transponders. The digital module manages the complete ISO/IEC 14443 A framing and error detection (parity and CRC) functionality.

Features : 

1. FIFO buffer handles 64 byte send and receive

2. Flexible interrupt modes

3. Hard reset with low power function

4. Power-down by software mode

5. Programmable timer
