Discovery kit for the M24SR series Dynamic NFC/RFID tag
Premium and Standard Editions
Introduction
The M24SR-DISCOVERY is a demonstration kit to evaluate the features and capabilities of
the M24SR series and is based on the M24SR64 device. Two versions of this kit are
available: the Standard Edition and the Premium Edition.
The Premium Edition includes all of the Standard edition features, plus a headset and a
Bluetooth module to demonstrate the convenience to pair it with a smartphone via NFC.
The M24SR64 device is a dynamic NFC/RFID tag IC with a dual interface. It embeds a
64 Kbits EEPROM memory. It can be operated from an I2C interface or by a 13.56 MHz
RFID reader or an NFC phone.
The I2C interface uses a two-wire serial interface, consisting of a bidirectional data line and
a clock line. It behaves as a slave with respect to the I2C protocol.
The RF protocol is compatible with ISO/IEC 14443 Type A and NFC Forum Type 4 Tag.
The board is powered through the USB bus. It also includes a microcontroller STM32F103
to drive the EEPROM via I2C and the LCD screen via SPI bus.
The M24SR-DISCOVERY (MB1138) schematics, BOM, gerber files, drivers and firmware
can be downloaded from www.st.com.

3 Hardware and layout description
The M24SR-DISCO board contains the M24SR64-Y chip. It is a dynamic NFC/RFID tag IC. It features
a 64 Kbits of EEPROM memory, preformatted for NFC transactions, and which can be protected by a
unique and flexible 128-bit password scheme. The memory bank can be accessed by any of its to
interfaces, either from an I2C interface or by a 13.56 MHz passive NFC interface. The I2C interface
uses a two-wire serial interface, consisting of a bidirectional data line and a clock line. It behaves as a
slave in the I2C protocol. The NFC interface is based on the ISO/IEC 14443 Type A and NFC Forum
Type 4 Tag specifications. Because it is a passive RF interface, it operates when the board is powered
but also when the board is unpowered. Two control pins are also available from the M24SR64-Y chip,
allowing flexible management of the NFC interface.

3.2 M24SR-Discovery board powering and startup
The M24SR-Discovery board is powered by the USB bus via a Type A / micro B USB cable
connected to a PC.
When powered up, the microcontroller starts the firmware already downloaded in the Flash
memory. This is a demonstration of the different capability of the M24SR64 (RF on/off,
change Vcard message, etc ). There is no modification or configuration to be done on the
board to run the demo. Please refer to the firmware user manual available on ST web site
www.st.com to get more detail.
3.3 Program and debug the M24SR-Discovery board
In order to flash or debug an STM32 microcontroller application on the M24SR-Discovery
board, simply connect the 20-pin JTAG/SWD flat ribbon of the STLINK/V2 in-circuit
debugger and programmer to the discovery kit board JTAG connector (J2).
Launch STLink Utility PC software. STM32F103RGT6 is part of the STM32F10x XL-density
family.
(It can be downloaded from ST web site: www.st.com)
For more information or documentation on the STLINK/V2 in-circuit debugger and
programmer, please visit www.st.com.
