Functional description

The M24SR02-Y device is a dynamic NFC/RFID tag that can be accessed either from the

I2C or the RF interface. The RF and I2C host can read or write to the same memory, that is

why only one host can communicate at a time with the M24SR02-Y. The management of

the interface selection is controlled by the M24SR02-Y device itself.

The RF interface is based on the ISO/IEC 14443 Type A standard. The M24SR02-Y is

compatible with the NFC Forum Type 4 Tag specifications and supports all corresponding

commands.

The I2C interface uses a two-wire serial interface consisting of a bidirectional data line and a

clock line. The devices carry a built-in 4-bit device type identifier code in accordance with

the I²C bus definition.

The device behaves as a slave in the I2C protocol.
