RENESAS PTX105RDQ56D13 RFID, Multi-Protocol NFC, Read, Write, 13.15MHz to 52MHz, 2.7 to 5.5V, 1W, HVQFN-56

PTX105RDQ56D13 is a PTX105R mid-power, multi-protocol NFC forum-compliant reader IC. It is a highly integrated NFC reader IC for contactless communication, which is optimized for reader performance and interoperability (Vcc current up to 500mA). While eliminating EMC filter and matching components, the PTX105R enables simple integration and compact design without the complexity associated with existing solutions (dual resonating circuits composed by EMC filter and antenna). Superior sensitivity, accurate digital wave shaping, and reduced bill-of-materials compared to conventional square-wave NFC controllers enable optimal interoperability, simplified FCC certification, and faster NFC Forum compliance. Typical applications are personal safety trackers, smart locks with super low power Wi-Fi and Bluetooth low energy, green 3-phase smart energy meters, IoT communications gateway hubs, 1-phase power meters, smart NFC access control systems.
