Description
The SPX-18991 NFC/RFID Tag is a Dynamic NFC/RFID Tag for smôl boards. The STMicroelectronics ST25FV64KC is a dynamic Near Frequency Communication / Radio Frequency Identification tag IC with 64Kbit (8KByte) of on-board EEPROM memory. It has an I2C interface which the smôl processor board can use to read and write to the EEPROM memory. The NFC/RFID tag peripheral board would also let you configure your smôl logging system.
ST25DV64KC Features:
-
Contactless interface
- Based on ISO/IEC 15693
- NFC Forum Type 5 tag certified by the NFC Forum
- Supports all ISO/IEC 15693 modulations, coding, sub-carrier modes and data rates
- Custom fast read access up to 53 kbit/s
- Single and multiple blocks read (same for Extended commands)
- Single and multiple blocks write (up to four) (same for Extended commands)
-
