The PTX105R is the industry’s best-performing NFC controller for Internet of Things applications. Due to its unique sine wave architecture, PTX105R is an optimized solution for IoT applications with small form factors. Superior sensitivity, accurate digital wave shaping, and a reduced bill-of-materials compared to conventional square-wave NFC controllers enable optimal interoperability, simplified FCC certification and faster NFC Forum compliance.

PTX105R NFC Controller Benefits

  • Easier to achieve interoperability with the broader set of more demanding NFC device form factors
  • Reliable NFC coupling in challenging operating environments, or with small form factor antenna
  • Supports operation through an antenna typically 4-5 times smaller than that required by conventional NFC readers
  • Fewer external components for bill-of-materials cost and space savings


  • Output power up to 1W @5V 
  • Very high Receiver sensitivity (-80dBc) 
  • Sine Wave output 
  • Accurate Digital Wave Shaping 
  • Removal of second resonating structure introduced by EMI 
  • DiRAC: Direct antenna connection 
  • NFC Split Stack handling Time critical commands 
  • Less packet exchanged between NFC and MCU 
  • Customer accessible GPIOs



  • Mid-power universal multi-market reader solutions

Innovative NFC Solution for IoT

The IoT market has been booming over the last few years, to say the least. By 2030 there will be approximately half a trillion IoT devices shipped to the market, and already by the end of 2021, almost 7 billion IoT devices shipped will be NFC enabled.

NFC contributes a big deal to the growth and development of IoT applications, enabling a variety of different features in different setups. Ranging from consumer devices to industry 4.0, electric vehicles, and smart home ecosystems – NFC is an integral part of any application design. Our products at Renesas are designed with the end application in mind.

In this video, we present to you the benefits that PTX100R brings to the IoT arena and what can be achieved by using our industry's best NFC IC.
