STMicroelectronics ST25DV64KC | Demoboard ST25DV64KC-DISCO
Dynamic NFC/RFID tag IC with 64-Kbit EEPROM, and fast transfer mode capability
Overview
| Topology | Other Topology |
| IC revision | 1 |
Description
The ST25DV64KC-DISCO is a demonstration kit to evaluate the features and capabilities of the ST25DVxxKC devices. It is based on the NFC ST25DV64KC device embedded on daughterboards using a Class 3 and 6 antenna and an STM32 processor driving a motherboard. A dedicated software stored in the Flash memory is provided. The ST25DV64KC device is a dynamic NFC/RFID tag IC with a dual interface. It embeds a 64 Kbits EEPROM. It can be operated from an I2C interface, or by a 13.56 MHz RFID reader, or by an NFC phone.The ST25DV64KC I2C interface uses a two-wire serial interface, consisting in a bidirectional data line and a clock line. The I2C two-wire serial interface behaves as a slave in the I2C protocol.The RF protocol is compatible with ISO/IEC 15693 and NFC Forum Type 5 tag contactless interface.The boards are powered through the USB connectors.The schematics, BOM, gerber files, drivers and firmware sources can be downloaded from www.st.com.
