Product details

Overview

M24SR-DISCOVERY from STMicroelectronics is a ready-to-use demonstration kit for the M24SR64 dynamic NFC/RFID tag IC, integrating an STM32F103RGT6 microcontroller (64LQFP, 1 MB Flash), a 320×200 color LCD, a 31 mm × 30 mm 13.56 MHz etched antenna, and USB-powered operation. It enables hands-on evaluation of dual-interface (I²C + ISO/IEC 14443 Type A/NFC Forum Type 4) EEPROM tag functionality in NFC pairing, secure data exchange, and embedded RFID prototyping.

For engineers reviewing the M24SR-DISCOVERY datasheet, M24SR-DISCOVERY pinout, M24SR-DISCOVERY application, or M24SR-DISCOVERY equivalent, this kit supports rapid validation of NFC-initiated I²C memory access, RF protocol interoperability with smartphones and readers, firmware-upgradable STM32-based UI control, and Bluetooth-augmented premium edition use cases.

Technical Context

The kit implements a complete NFC tag evaluation platform where the M24SR64 IC operates as a dual-interface slave device: its I²C interface (address 0x50) connects to the STM32F103's I²C1 peripheral, while its RF interface complies fully with ISO/IEC 14443 Type A and NFC Forum Type 4 Tag Operation. The STM32F103 drives the LCD via SPI and manages user input through a 5-way joystick.

Power is delivered exclusively via USB micro-B (5 V), regulated locally to 3.3 V for digital logic and antenna driver circuitry. The board includes JTAG (SWD) headers for firmware development and supports both Standard and Premium editions - the latter adds a Bluetooth audio module with 3.5 mm jack output and headset support.

FAQ

What interfaces does the M24SR64 IC support on this board?

The M24SR64 IC on the M24SR-DISCOVERY supports two concurrent interfaces: a standard I²C bus (7-bit address 0x50) connecting to the STM32F103's I²C1 peripheral, and a 13.56 MHz RF interface compliant with ISO/IEC 14443 Type A and NFC Forum Type 4 Tag Operation - enabling simultaneous wired and contactless memory access.

Does the board require external power or drivers to operate?

No external power is required: the board is fully USB-powered via the micro-B connector (5 V). Preloaded firmware enables immediate operation; ST provides all necessary drivers, sample code, and PC software tools free of charge on www.st.com under the M24SR-DISCOVERY resource page, including STM32Cube firmware packages and NFC demo applications.

How does the Premium Edition differ from the Standard Edition?

The M24SR-DISCO-PREM adds a Bluetooth audio module with stereo line-out via 3.5 mm jack and integrated headset support - enabling NFC-triggered Bluetooth pairing and audio streaming demos. All Standard Edition features (LCD, joystick, antenna, USB/JTAG) are retained; no hardware changes affect core NFC/I²C functionality or firmware compatibility.

Can the STM32 firmware be customized or reprogrammed?

Yes - the board includes a standard SWD/JTAG connector compatible with ST-LINK/V2 and other ARM debug probes. Full source firmware, HAL libraries, and Keil/IAR/STM32CubeIDE project files are available from ST's official website, allowing full customization of LCD UI, NFC command handling, I²C memory mapping, and Bluetooth interaction logic.
