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.
