ST ST25TA02KB-DC6H5

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.
