2. Features and benefits 2.1 Key features ? RF interface NFC Forum Type 2 Tag compliant ? I 2C interface ? Configurable field detection pin based on open drain implementation that can be triggered upon the following events: ? RF field presence ? First start of communication

 ? Selection of the tag only ? 64 byte SRAM buffer for fast transfer of data (Pass-through mode) between the RF and the I2C interfaces located outside the User Memory ? Wake up signal at the field detect pin when: ? New data has arrived from one interface ? Data has been 

read by the receiving interface ? Clear arbitration between RF and I2C interfaces: ? First come, first serve strategy ? Status flag bits to signal if one interface is busy writing to or reading data from the EEPROM ? Energy harvesting functionality to power external devices (e.g. microcontroller) ? FAST READ command for faster data reading 2.2 RF interface ? Contactless transmission of data ? NFC Forum Type 2 Tag compliant (see Ref. 1) ? Operating frequency of 13.56 MHz ? Data transfer of 106 kbit/s ? 4 bytes (one page) written including all overhead in 4.8 ms via EEPROM or 0.8 ms via SRAM (Pass-through mode) ? Data integrity of 16-bit CRC, parity, bit coding, bit counting ? Operating distance of up to 100 mm (depending on various parameters, such as field strength and antenna geometry) ? True anticollision ? Unique 7 byte serial number (cascade level 2 according to ISO/IEC 14443-3 (see Ref. 2) 2.3 Memory ? 1904 bytes freely available with User Read/Write area (476 pages with 4 bytes per pages) for the NTAG I2C 2k version ? 888 bytes freely available with User Read/Write area (222 pages with 4 bytes per pages) for the NTAG I2C 1k version ? Field programmable RF read-only locking function with static and dynamic lock bits configurable from both I2C and NFC interfaces ? 64 bytes SRAM volatile memory without write endurance limitation
