Features
I2C interface
• Two-wire I2C serial interface supports 1MHz protocol
• Single supply voltage: 1.8V to 5.5V
• Multiple byte write programming (up to 256 bytes)
Contactless interface
• Based on ISO/IEC 15693
• NFC Forum Type 5 tag certified by the NFC Forum
• Supports all ISO/IEC 15693 modulations, coding, sub-carrier modes and data
rates
• Custom fast read access up to 53 Kbit/s
• Single and multiple blocks read (same for Extended commands)
• Single and multiple blocks write (up to 4) (same for Extended commands)
• Internal tuning capacitance: 28.5 pF
Memory
• Up to 64-kbits of EEPROM (depending on version)
• I2C interface accesses bytes
• RF interface accesses blocks of 4 bytes
• Write time:
– From I2C: typical 5ms for 1 byte
– From RF: typical 5ms for 1 block
• Data retention: 40 years
• Write cycles endurance:
– 1 million write cycles at 25 °C
– 600k write cycles at 85 °C
– 500k write cycles at 105 °C
– 400k write cycles at 125 °C
Fast transfer mode
• Fast data transfer between I2C and RF interfaces
• Half-duplex 256-byte dedicated buffer
Energy harvesting
• Analog output pin to power external components
Data protection
• User memory: 1 to 4 configurable areas, protectable in read and/or write by
three 64-bit passwords in RF and one 64-bit password in I2C
• System configuration: protected in write by a 64-bit password in RF and a 64-bit
password in I2C
