Description

The ST25TV16K and ST25TV64K devices are NFC and RFID tags, with, respectively, 16 and 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.

? Kill capability for privacy protection

Memory

? 16 or 64 Kbits of EEPROM

? RF interface accesses blocks of four bytes

? Typical write time: 5 ms for one block

? Data retention: 40 years

? Write cycles endurance:

– 1 million at 25 °C

– 600 k at 85 °C

Data protection

? User memory: one to four configurable areas, protectable in read and/or write

by three 64-bit passwords

? System configuration: protected in write by a 64-bit password

Temperature range

? From -40 to 85 °C
