Introduction
The M24LR-DISCOVERY kit helps you evaluate the M24LRXX-E Dual Interface EEPROM that features
an energy harvesting analog output, as well as a user-configurable digital output.
The M24LR-DISCOVERY kit is delivered with a battery-less M24LR board that can be powered by RFID
readers or NFC phones supporting the ISO/IEC15693 protocol. It is based on an M24LR04E-R I²C -
ISO/IEC15693 Dual Interface EEPROM, an 8-bit STM8L152C6T6 ultralow power microcontroller, and
includes an STTS751 temperature sensor, a 24-segment LCD, and 2 push buttons.
The M24LR-DISCOVERY kit also comes with an USB RF transceiver demonstration board that includes
the CR95HF 13.56-MHz multi-protocol contactless transceiver. It is based on a 32-bit, STM32F103CBT6
performance line microcontroller and is connected to a computer host via its USB connector.

Page 9: M24Lr Board Power Selection
UM1589 Hardware and layout description M24LR board power selection When jumper JP1 is set in the “RF power” position (Figure 4), the M24LR board is powered by the M24LR04E-R energy harvesting analog output (Vout pin). In this configuration, the M24LR board is powered by the magnetic field flowing into its 9-turn, etched loop antenna, delivered from a 13.56-MHz RF source, such as an RFID reader or an NFC phone. -
