Automotive : Body Systems : NFC Wireless Charging reference design (WCT-5WTXAUTO)

The reference design WCT-5WTXAUTO is a complete and unique solution, demonstrating the coexistence of both Wireless Charging Transmitter (WCT) and Near Field Communication (NFC) technologies on a single and easy-to-use module. The reference design includes all the required hardware and associated software drivers to allow a fully autonomous behavior of the WPC subsystem, controlled via a standard compliant NFC Control Interface (NCI). The co-existence is managed on the hardware side through a careful antenna design and on the software side via dedicated control interface.

The NFC operation of this reference design is performed using the automotive compliant MLX90132 13.56MHz NFC transceiver IC, developed and produced by Melexis. The NFC analogue part embeds a minimum set of components around the MLX90132 IC to make it functional as an NFCIP-2 reader which conforms to following standards: Reader/Writer (ISO/IEC14443, ISO/IEC18092 and ISO/IEC15693), Peer-To-Peer Passive communication Initiator/Target and TAG Emulation (ISO/IEC14443 and ISO/IEC18092). The reference Design uses an on-PCB printed NFC antenna with an optimized matching network taking into consideration the detuning operated by the presence of wireless charging coils, for the maximum performances.

The MLX90132 is connected to the microcontroller WCT1003A from the company Freescale® supporting the NFC low-layer stack LLS, composed of the hardware abstraction layer (HAL-90132) and the NCI compliant interface, as well as the Wireless Charging stack developed by Freescale®. The NFC Upper-Layer-Stack (ULS) is composed of the NFCStack+ SDK from the company Stollmann®. The Reference design is connected to a computer through the UART-to-USB interface.
