Product details
Overview
M24LR-DISCOVERY from STMicroelectronics is an evaluation kit comprising two interoperable PCBs: an M24LR board featuring the M24LR04E-R dual-interface EEPROM (I²C + ISO/IEC 15693), STM8L152C6T6 MCU, STTS751 temperature sensor, and LCD; and an RF transceiver board with CR95HF-VMD5T IC, STM32F103CB MCU, and USB-host interface - designed for NFC/RFID system prototyping in industrial, medical, and consumer electronics.
For engineers reviewing the M24LR-DISCOVERY datasheet, M24LR-DISCOVERY pinout, M24LR-DISCOVERY application, or M24LR-DISCOVERY equivalent, this kit enables rapid validation of energy-harvesting RFID tag operation, NDEF message exchange, and dual-interface EEPROM integration without external power on the tag side.
Technical Context
The M24LR-DISCOVERY implements a complete ISO/IEC 15693 RFID system: the M24LR board acts as a passive, battery-less tag powered via RF coupling (13.56 MHz), while the RF transceiver board serves as a PC-connected reader using CR95HF's SPI/UART interfaces and integrated antenna matching circuitry.
It supports NDEF message read/write operations via Android NFC phones (using NfcV-Reader app) and PC-based demonstration software (STSW-M24LR011), with real-time display of EEPROM-stored text, harvested voltage, and ambient temperature on the onboard 24-segment LCD.

FAQ
Does M24LR-DISCOVERY require external power for the M24LR board?
No. The M24LR board is fully passive and derives operating power solely from the RF field generated by an ISO/IEC 15693 reader or NFC-enabled smartphone. Its M24LR04E-R EEPROM and STM8L152C6T6 MCU operate within the harvested voltage range (typically 1.8–3.6 V), enabling battery-free operation during tag interrogation.
What software tools are included with M24LR-DISCOVERY?
The kit ships with preloaded STM8L firmware and supports two software environments: PC-based STSW-M24LR011 demonstration software (for CR95HF reader control, NDEF messaging, and energy harvesting monitoring) and the Android NfcV-Reader app from Google Play for direct phone-to-tag interaction and NDEF write capability.
Can the M24LR-DISCOVERY be used to develop custom firmware?
Yes. Both MCUs are fully programmable: the STM8L152C6T6 on the M24LR board supports SWIM debugging and reprogramming via the onboard connector; the STM32F103CB on the RF transceiver board supports SWD/JTAG and can be reprogrammed using ST's STM32CubeIDE or Keil MDK, with source code available from ST's website.
Is the M24LR-DISCOVERY compatible with ISO/IEC 14443 readers?
No. The M24LR-DISCOVERY is specifically designed for ISO/IEC 15693 (vicinity) operation at 13.56 MHz. It does not support ISO/IEC 14443 (proximity) protocols such as those used by MIFARE or standard NFC cards. Compatibility is limited to 15693-compliant readers and NFC phones with ISO/IEC 15693 mode enabled.
