NFC-Forum Type 2 Tag


NFC-Forum Type 2 Tag with UART Interface

Able to harvest power from NFC devices up to 10 mA and allows external devices for passive operation mode

Key Features

  • Energy Harvesting
  • UART and GPIO Interface


The SIC4310 is a dual-port, 228-byte, NFC-tag IC with an UART interface. The EEPROM memory can be accessed via either NFC/RFID reader devices or UART and is organized to be compliant with NFC Forum Tag Type 2. Apart from the memory device, the SIC4310 is intended to be a protocol converter that avails direct transparent data transfer from NFC device to UART or vice versa as well. The UART interface facilitates data communication with various kinds of devices for multipurpose applications such as MCUs or sensor modules.
