STMicroelectronics ST25TV04K-P
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.FEATURES
