M24SR02-YMN6T/2

The M24SR02-YMN6T/2 is a STMicroelectronics dynamic NFC/RFID tag. It blends a 2‑Kbit EEPROM with a dual interface: an I2C interface for an external microcontroller (SDA/SCL) and a contactless NFC RF interface (NFC Forum Type 5 / ISO/IEC 15693). The device can be powered by the NFC field during RF operation or from a supply via I2C.
Memory and access: about 256 bytes of EEPROM accessible via either interface, with features common to dynamic tags such as memory updates in RF mode and basic security options (e.g., protection/locking).
Packaging variant: the suffix YMN6T/2 denotes the specific package and temp rating for this part; exact pins, voltage range, timings, and security capabilities are in the datasheet.
Applications: NFC-enabled tagging for asset tracking, product authentication, smart posters, configuration data storage, and simple data logging.
For precise electrical specs and pinout, consult the M24SR02-YMN6T/2 datasheet.

Equivalent products include:
- ST25DV02K (2 kbit dynamic NFC/RFID tag with I2C)
- NXP NTAG I2C Plus family (2 kbit dynamic NFC tags with I2C interface)

Here are the core features of M24SR02-YMN6T/2:
- Dual interface: I2C bus for host MCU and NFC/RFID interface (ISO/IEC 15693, NFC Forum Type 5 Tag).
