STMicroelectronics ST25TV64KC-APG3 RFID and NFC Transceiver 120um +/- 15um bumped sawn wafer

The STMicroelectronics RFID tag IC with 16-Kbit EEPROM and protection are NFC and RFID tags, with, respectively, 64 Kbit of electrically erasable programmable memory (EEPROM). These devices act as a contactless memory accessed through an RF link, following ISO/IEC 15693 or NFC Forum Type 5 recommendations, and are powered by the received carrier electromagnetic wave.

NFC Forum Type 5 tag certified by the NFC Forum
Custom fast read access up to 53 Kbit/s
Single and multiple block reads (same for extended commands)
Single and multiple block writes (same for extended commands) up to four
Internal tuning capacitance 28.5 pF
