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.

NFC Reader for Internet of Things Applications
PTX105R provides manufacturers of NFC enabled devices with valuable 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
The PTX105R is in mass production now.
