Overview

Description

The PTX105REK enables quick evaluation of the PTX105R NFC reader IC for IoT applications. The PTX105R is an optimized solution for IoT applications with small form factors due to its unique sine wave architecture. Superior sensitivity, precise digital wave shaping, and a streamlined bill of materials compared to conventional square-wave NFC controllers deliver optimal interoperability, simplify FCC certification, and accelerate NFC Forum compliance.

Features

  • Mid-power NFC Reader Kit (1W) for universal reader hardware platform IC PTX105R
  • Plug-and-play software integration for any terminal or device host MCU architecture, supporting all major NFC protocols and standards:
    • ISO 14443 A/B
    • ISO 18092
    • ISO 15693
    • FeliCa and others
  • Supports NFC P2P Initiator and Host Card Emulation (HCE)
  • Digital Dynamic Power Control (DDPC) and DIRAC® technology for EMI filter-less operation, advanced digital wave-shaping, phase-accurate active load modulation in card mode, and very high dynamic range receiver (VHDRR)
  • RF design support with configuration tool and SDKs

  1. NFC antenna resistors

    I'm confused about resistors that are used to ground NFC antenna pins on PTX100REK, PTX105REK and PTX130REK boards. There's no mention of them in the datasheets and they are not present on PTX105RQC. But PTX105REK has a pair of 910R probably 0603 or 0805 size and PTX100REK/ ...
