STMicroelectronics DEMOKIT-M24LR-A

Overview

DEMOKIT-M24LR-A from STMicroelectronics is a demonstration kit for the M24LRxx series of dual-interface (RF + I²C) EEPROMs, enabling hands-on evaluation of ISO/IEC 15693 RFID communication and contact-based memory access. It includes reference antennas (ANT1-M24LR-A and ANT2-M24LR-A), supports energy harvesting mode, and targets NFC/RFID tag development, smart label prototyping, and embedded system integration with passive RF coupling.

For engineers reviewing the DEMOKIT-M24LR-A datasheet, DEMOKIT-M24LR-A pinout, DEMOKIT-M24LR-A application, or DEMOKIT-M24LR-A equivalent, this kit provides direct validation of RF inventory, UID read/write, sector security configuration, I²C memory mapping, and dual-channel command coordination - essential for industrial asset tagging, electronic shelf label (ESL) design, and battery-free sensor node development.

Technical Context

The DEMOKIT-M24LR-A is not a semiconductor component but a hardware evaluation platform built around the M24LR64-R EEPROM in SO8 package. It interfaces with ST's M24LRxx_Application_Software to execute ISO/IEC 15693 RF commands (e.g., Inventory, Read, Write, Lock AFI/DSFID) and I²C commands (Read/Write memory array, sector security status, password management).

It enables real-time visualization of RF request/answer sequences, dual-mode state management (Addressed/Non-addressed/Select), and energy harvesting command testing. The kit supports image transfer demos, STM32-PRIMER2-based I²C readout, datalogger simulation, and ESL-style display updates - all via a Windows GUI application.

FAQ

What hardware components are included in the DEMOKIT-M24LR-A?

The DEMOKIT-M24LR-A includes two reference antennas (ANT1-M24LR-A and ANT2-M24LR-A), an M24LR64-R EEPROM mounted on a demo board, and full compatibility with ST's CR95HF-A RF reader and STM32-PRIMER2 development platform. No MCU or host processor is integrated - it functions as a passive tag evaluation platform with external interface requirements.

Does the DEMOKIT-M24LR-A require external power during RF operation?

No - the M24LR64-R device in the kit operates in passive mode during RF communication, drawing power from the RF field generated by a compatible ISO/IEC 15693 reader (e.g., CR95HF-A). I²C operations require separate 1.8–5.5 V DC supply via the connected host system or evaluation board.

Can the DEMOKIT-M24LR-A be used to develop custom firmware for M24LRxx devices?

No - the kit does not provide programming or debug interfaces for firmware modification. It is strictly a hardware/software demonstration platform for evaluating pre-programmed M24LRxx EEPROM functionality using ST's M24LRxx_Application_Software GUI and predefined demo workflows (e.g., image transfer, ESL update).

Is the M24LRxx_Application_Software compatible with modern Windows OS versions?

Yes - while originally released for Windows XP/Vista/7, the M24LRxx_Application_Software has been verified to run on Windows 10 and Windows 11 under compatibility mode. USB-to-serial drivers for associated readers (e.g., CR95HF-A) are required and available from ST's official support portal.
