Contactless IC Chip


Contactless IC Chip


NFC Module with I2C Interface


  • Wide range of functions and operational modes
  • Power-saving
  • Conforms to international standards

FeliCa™ Link inherits the functionality of FeliCa Plug and FeliCa Lite-S. In addition, it supports reader/writer functionality as well as NFC-DEP function.
IC chip RC-S967/1V provides NFC Tag functionality.
IC chip RC-S967/2V supports reader/writer functionality, in addition to functions provided by RC-S967/1V.
RC-S730 is an NFC module with I2C interface, based on the RC-S967/1V IC chip.


Various functions and mode of operation

Thanks to the NFC-F function for Near Field Communication and an I2C (Inter-Integrated Circuit) bus for wired communication, data exchange is possible between smartphones equipped with NFC and the controller (Host CPU) of a device incorporating this product. The five modes (Lite-S, Lite-S HT*1, Plug, NFC-DEP, and Reader/Writer*2) enable a variety of applications to be used.
Mutual authentication functionality using MAC (Message Authentication Code) is also implemented.


A maximum 0.5 mA current supply is consumed during operation, which drops to only 0.1 μA during standby, making the product suitable for installation in battery-operated electronic devices. To save battery power, the functionality that detects the magnetic field and commands from the reader can be used to control the power-saving mode.

Conforms to international standards

The product Conforms to NFC Type 3 Tag as defined by the NFC Forum, supporting P2P communication (NFC-DEP)*3, therefore it enables communication with NFC smartphones and other NFC devices.
In addition, the NFC module with I2C interface (RC-S730) can communicate with devices that incorporate any of the three reference antenna types (P0, P3, and P6 size) of the NFC Forum's 2nd Wave Certification*4.

*1 Lite-S HT stands for Lite-S Host Through mode.
*2 Operates only with RC-S967/2V. In addition to this product, a carrier-wave generating circuit and antenna are required.
*3 On the controller side of the device in which this product has been incorporated, NFC-DEP, LLCP, and SNEP protocol stacks must be implemented, as defined by the NFC Forum.
*4 The communication performance is promised on the ideal environment without the effects of peripheral radio frequencies and/or metal obstructions.
