The PTX100W reference design provides manufacturers of wearable and portable devices with a blueprint for a complete system design, including hardware schematics and Gerber files for both the poller and listener circuits, and separate software development kits (SDKs) for the poller and listener. In addition to the PTX100W near-field communication (NFC) controller from Panthronics, the reference design supports Renesas RA 32-bit microcontrollers (MCUs) and Renesas Synergy MCUs for system control in the poller and listener circuits.


  • NFC wireless charging SDKs for high-power, high-performance PTX100W NFC wireless charging (WLC) platform.
  • Easy-to-use, ready-to-go software integration.
  • Discrete high-power harvesting WLC listener boards with PMIC and MCU.
  • Convergence with reader functions supporting all types of NFC and standard protocols (ISO 14443 A/B, ISO 18092, ISO 15693, FeliCa).
  • EMI filterless (DiRAC®) high-power end-application RF-design supported with configuration tool SDK.
