FeliCa Lite-S Compact Antenna Module



  • Compact and energy-saving
  • NFC Type 3 Tag
  • PAD for an external circuit

The RC-S711 / RC-S712 products are compact antenna modules equipped with a FeliCa™ Lite-S chip compatible with the NFC Forum Type 3 Tag. They are suitable for embedding into consumer digital devices.


The compact antenna modules equipped with a compact and power-saving IC can be set up easily in consumer digital devices. The RC-S711 / RC-S712 modules have a function to detect magnetic fields in contactless communication and then inform the host, so they are well-suited to connection handover to Bluetooth and Wi-Fi communication with other NFC devices.


Compact and energy-saving design

The RC-S711 / RC-S712 modules are equipped with an energy-saving custom IC chip that operates with a low-strength electromagnetic field.

Compatibility of NFC Forum Type 3 Tag

The RC-S711 / RC-S712 modules support NFC Forum Type 3 Tag operations. Therefore, they can communicate with any reader that is compliant with the NFC Forum specification.
The user memory of 224 bytes is sufficient for most NFC-tag applications and usages.

External PAD for transmission of magnetic field detection signal

The NFC Tag module has a function by which the magnetic field generated by the reader can be detected, and sends a wake-up signal to the host CPU through the wire connected to the external pads.

Mutual authentication function utilizing MAC (Message Authentication Code)

The RC-S711 / RC-S712 modules are equipped with a simple authentication function, unlike the conventional FeliCa chip. By adding a MAC to the data being read, authenticity can be verified by the reader.

Simple file system

Despite the simple non-hierarchical file system structure, two access attributes, including "read-only" or "read-write" of stored data can be set for each data block.

Anti-tearing transaction function and data integrity-check function

This product has anti-tearing transaction functionality to prevent incomplete data update. Even if a data error occurs in the chip, any failed transaction results in the data being replaced by the previously stored data.
