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
