M24SR-DISCOVERY
Description
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.
