Description

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.
