Product Overview
ST25R3920-AQWT is a automotive high performance NFC reader for CCC digital key and car centre console. It enables fast product development for car access/start applications in areas like door handle or centre console and enables additional functionality like pairing or NFC card protection combined with a Qi charger. Being very robust and noise tolerant. At the same time reducing electromagnetic emission, the device works even under harsh conditions enabling an easier certification. It features high RF power with dynamic power output to directly drive into antennas at high efficiency. The device include additional features like incomparable for low power applications. It offers low power card detection by performing a measurement of the amplitude or phase of the antenna signal while reducing power consumption to a minimum. Additionally it contains a low power capacitive sensor to detect the presence of a card without switching on the reader field.
