The PTX100R NFC reader serves IoT and Point-of-Sale (PoS) applications, implementing a unique sine wave hardware transceiver architecture and offering a winning combination of superior transmit power and sensitivity, accurate wave shaping, and a reduced bill-of-materials compared to conventional square-wave NFC controllers – products which have changed little over the past decade.

The PTX100R marks a breakthrough in NFC system performance, power and integration simplicity.

This NFC reader IC is fully compliant with the specifications of the latest EMVCo 3.0/3.1 standard for contactless payments. It is supplied with an application-ready EMVCo 3.0/3.1 L1 interface and includes a set of facilities that makes the integration of a third-party EMV L2 stack fast and easy. It also provides rich debugging capabilities allowing for rapid prototyping.

Benefit from our patented Direct Antenna Connection (DiRAC™) technology which enables the NFC to drive output power of up to 2W directly to the antenna while achieving a sensitivity of -80dB.


  • High output power up to 2W @5.5V
  • Very high Receiver sensitivity (-80dBc)
  • DiRAC: Direct antenna connection for Tx and Rx
  • Sine Wave output Accurate Digital Wave Shaping
  • Removal of second resonating structure introduced by EMI
  • Xtal-less design using reference clock



  • EMVCo 3.0/3.1 Point-of-Sale (PoS) systems
  • High-end IoT applications

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.
