描述 Description

The ST25TA512B and ST25TA02KB devices are NFC tag ICs, with an optional general purpose output available on ST25TA02KB-D and ST25TA02KB-P.

They embed an up to 2 -Kbit EEPROM, and can be operated from a 13.56 MHz RFID reader or an NFC phone.

The ST25TA512B, ST25TA02KB,

ST25TA02KB-D and ST25TA02KB-P devices are NFC Forum Type 4 Tags.

They communicate using the ISO/IEC 14443 Type A protocol, and feature a digital signature generated by TruST25? (a set of software and procedures) used to prove the origin of the chip in cloning detection.
