It features 2KB EEPROM (1912 bytes freely available user memory) and a 64-byte SRAM buffer for bidirectional data transfer between the NFC and I2C interfaces. The device maintains full backward compatibility with first-generation NTAG I2C while adding advanced features including 32-bit password protection, full memory-access configuration from both interfaces, and an ECC-based originality signature for cloning protection. It supports energy harvesting from the NFC field (up to 15 mW) to power external devices and features a configurable field detection pin for wake-up functionality. The device is NFC Forum Type 2 Tag certified (Certification ID: 58514).","working_principle":"The NT3H2211W0FTTJ operates through two communication interfaces: an NFC interface (ISO\/IEC 14443A at 106 kbit\/s, powered by the NFC reader's RF field) and an I2C slave interface (up to 400 kHz, powered by the host VCC). The 64-byte SRAM buffer enables pass-through mode for bidirectional data transfer between the two interfaces without writing to EEPROM. Memory arbitration ensures conflict-free access \u2014 when one interface is writing, the other is blocked via session registers. The energy harvesting feature extracts power from the NFC field to supply external circuitry via the VOUT pin. The field detection (FD) pin signals NFC field presence or data synchronization events to the host. Password protection (32-bit) restricts memory access from the NFC interface, while the I2C interface can independently configure access rights. The ECC originality signature provides authentication against cloning.","pin_description":"\n
