产品概述

描述

The ST25R3920 is an automotive grade high performance NFC universal device supporting NFC initiator, NFC target, NFC reader and NFC card emulation modes.

Ideally fitting the CCC (car connectivity consortium) digital key specifications, the ST25R3920 satisfies the requirements for car access/start applications in areas like door handle or center console, and enables additional functionality, like pairing or NFC card protection combined with a Qi charger. Being very robust and noise tolerant while reducing electromagnetic emission, the device works even under harsh conditions, enabling an easier certification.

The device includes an advanced analog front end (AFE) and a highly integrated data framing system for ISO18092 passive and active initiator, ISO 18092 passive and active target, NFC-A/B (ISO14443A/B) reader including higher bit rates, NFC-F (FeliCa™) reader, NFC-V (ISO15693) reader up to 53 kbps, and NFC-A / NFC-F card emulation.

Special stream and transparent modes of the AFE and framing system can be used to implement other custom protocols in reader or card emulation modes.

The ST25R3920 features high RF power with dynamic power output to directly drive antennas at high efficiency, achieving large interaction distance even with small antenna sizes common in door handles. The device include additional features, making it 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.

The ST25R3920 is designed to operate from a wide power supply range (2.6 to 5.5 V from-40 °C to +105 °C, 2.4 to 5.5 V from -20 °C to +105 °C), and a wide peripheral IO voltage range (from 1.65 to 5.5 V).

Due to this combination of high RF output power, low power modes, wide supply range and AEC-Q100 grade 2 qualification the device is perfectly suited for automotive applications.
