PTX105R Multi-protocol NFC Forum Compliant Reader

Description

The PTX105R is a highly optimized NFC controller designed for compact IoT applications. It features superior sensitivity, precise digital sine wave shaping, and a reduced bill of materials compared to traditional square-wave NFC controllers. These advantages enable enhanced interoperability, streamlined FCC certification, and faster NFC Forum compliance.

The PTX105R also supports full end-to-end IoT go-to-market (GTM) integration through its compatibility with the RA microcontroller ecosystem. It is available via hardware modules on the QuickConnect platform and is also supported through the Arduino shield platform, enabling faster prototyping and deployment.

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 a 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
Comprehensive IoT go-to-market support for accelerated prototyping and deployment
