FLEX-M24LR04E

The FLEX-M24LR04E is a flexible antenna reference board. This is a ready to use flexible PCB that features an M24LR04E dual interface EEPROM IC connected to a 45mm x 75mm 13.56MHz etched RF antenna on one side and to an I2C bus on the other side. 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 FLEX-M24LR04E antenna allows system designers to evaluate the M24LR04E performance and capabilities, and to get started with their design. To demonstrate the energy harvesting function, the FLEX-M24LR04E can be used in conjunction with ST DEMO-CR95HF-A demonstration board. The application can be powered directly from the M24LR04E VOUT pin.
