M24LR-DISCOVERY

The M24LR-DISCOVERY is a ready to use discovery kit which features the M24LR04E-R dual interface EEPROM IC. The M24LR04E-R device is a dynamic NFC/RFID tag IC with a dual interface, electrically erasable programmable memory (EEPROM). It features an I2C interface and can be operated from a VCC power supply. It is also a contactless memory powered by the received carrier electromagnetic wave. The M24LR board is battery less and is powered by RFID readers or NFC enabled phones supporting ISO/IEC 15693. The RF transceiver board is an RFID reader demonstration board and is composed, among other parts, of a CR95HF (13.56MHz multi protocol contactless transceiver IC with SPI and UART serial access). This board has to be plugged in to a PC and comes with a demonstration software. The M24LR board also works with Android NFC phones supporting ISO/IEC 15693. An application called NfcV reader is available on Google Play. Performance may vary depending on NFC phone's RF management.
