Features
I2C interface
Two-wire I2C serial interface supports 1 MHz protocol Single supply voltage: 1.8 to 5.5 V Multiple byte 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 (up to 4) blocks write (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 5 ms for 1 byte – From RF: typical 5 ms for 1 block Data retention: 40 years Write cycles endurance: – 1 million at 25 °C – 600 k at 85 °C – 500 k at 105 °C – 400 k at 125 °C
