Renesas PTX105R NFC Controller

An industry-first for IoT

The PTX105R by Renesas is an ideal NFC solution for small form factor IoT applications. Featuring high-sensitivity, accurate digital wave shaping, and a reduced BOM compared to conventional square-wave NFC controllers, this solution enables optimal interoperability, simplified FCC certification and faster NFC forum compliance.

Due to its modular Soft Controller architecture, the NFC functionalities are integrated into a split stack solution where time-critical operations are running on the on-chip MCU, and the rest of the NFC logic is in the host controller to carry out applications such as IOT reader and POS.
