Description
The PTX205R is a highly integrated, mid-power NFC controller for NFC Forum applications, supporting reader/writer, card emulation, and peer-to-peer modes. Its patented Switched-Capacitor Power Amplifier (SCPA) architecture enables a sine-wave driver that simplifies system integration, supports compact antenna designs, and ensures best-in-class interoperability with existing NFC ecosystems. The modular NFC Soft Controller (NSC) architecture, combined with the advanced Split Stack software framework, enables the separation of time-critical operations, executed on the on-chip MCU, from high-level functionality running on the host controller. The result is a streamlined design that ensures real-time responsiveness while enabling implementation on cost-efficient host systems.
