Introduction
This document describes the functionalities of the STSW-ST25DV002 firmware, developed to take full advantage of the
ST25DV64KC-DISCO board functionalities, working with any dynamic tag of the ST25DV-I2C Series.
In this document, the dynamic tag series from STMicroelecronics is referred to as ST25DV-I2C tags.
The ST25DV-I2C tags are integrated circuits (IC) for contactless applications that communicate with a microcontroller through
an I
2
C interface; this makes this device a dynamic tag. On the RF side, the reader (for instance a smart phone) retrieves and
updates the content of the tag when close by.
The reader communicates with the ST25DV64KC-DISCO board using the ISO 15693 protocol, while the STM32L476xx
microcontroller device communicates with the ST25DV-I2C tag through an I
2
C bus.
With this discovery kit, the ST25DV-I2C tag is ready to receive any content, following the NFC Forum standard. This means that
a smart phone is able to natively read it, without having previously installed any specific application.
A specific Fast transfer mode allows the user to transfer data directly to the microcontroller, without using the embedded
EEPROM.
