製品概要

概要

The ST25TV04K-P device is a NFC and RFID tags, with 4 Kbits of electrically erasable programmable memory (EEPROM). This devie acts as a contactless memory accessed through a RF link, following ISO/IEC 15693 or NFC forum type 5 recommendations, and powered by the received carrier electromagnetic wave.

The GPO pin of the ST25TV04K-P provides data informing the contact world about incoming events, like RF field detection, RF activity in progress or can be directly controller by an RF reader. An energy harvesting feature is also proposed when external conditions make it possible.
