It integrates the complete analog and digital functionality needed for MIFARE Classic card reading, including authentication, encryption, and anti-collision handling. The device features a 64-byte FIFO buffer, programmable CRC coprocessor, and supports parallel, SPI, and EPP host interfaces. Housed in a SOIC-32 package, it operates from a single 5V supply with 25mA typical current consumption. Note: This device has been declared Obsolete and is no longer in production.","working_principle":"The MFRC500 generates a 13.56 MHz RF field through an external antenna to communicate with contactless cards. It modulates the carrier using 100% ASK for Type A communication and demodulates the load-modulated signal from the card. The internal MIFARE crypto engine handles the three-pass mutual authentication protocol with MIFARE Classic cards. The 64-byte FIFO buffer manages data flow between the host and the RF interface, while the CRC coprocessor offloads checksum calculations. Multiple interrupt sources enable efficient host processing through the IRQ pin.","pin_description":"
