M24LR-DISCOVERY

M24LR - Dual Interface EEPROM with I2C evaluation kit


M24LR-DISCOVERY is a ready-to-use kit which features the M24LR04E-R Dual Interface EEPROM IC. It addresses a wide range of applications such as industrial or medical equipment and consumer electronics. This kit contains 2 different boards (see Figure 1):

• 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 (13.56 MHz 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.
