4 Firmware description
4.1 Prerequisite
The ST25DV-I2C tag is a dynamic tag, whose content and configuration is driven by both a microcontroller
(through I²C) and a reader through RF.
To benefit from the ST25DV64KC-DISCO demonstration kit, the user must have one of the following:
•
A smart phone with the NFC enabled, combined with the ST25 NFC App installed on it. Refer to ST25
Android
™
NFC tap application (UM2131), available on www.st.com for more information.
• An NFC reader, such as the CR95HF distributed with the M24LR discovery kit (M24LR-DISCOVERY). To
take full advantage of the ST25DV-I2C tag features, use CR95HF transceiver board firmware version 3.7.0
or higher, combined with the ST25PC-NFC software. Refer to
Software toolbox for NFC tags user manual
(UM2444), available on www.st.com .
The ST25DV-I2C tag is fully compliant with the NFC Forum Type 5 standard. As this standard is recently
introduced, some features may not be fully supported by older smart phones.
