製品概要
概要
The ST25R500 is an automotive grade high-performance NFC universal device supporting NFC initiator, NFC target, NFC reader, and NFC card emulation modes. Designed for CCC (Car Connectivity Consortium®) digital key applications, the device enables fast product development 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 at the same time 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 NFC‑A/B (ISO/IEC 14443A/B) reader, including higher bit rates, NFC-F (FeliCa™) reader, NFC-V (ISO/IEC 15693) reader up to 212 kbps, and NFC‑A/NFC‑F card emulation.
It meets the most demanding requirements set by car and phone OEMs, delivering market-leading performance and ensuring a superior user experience.
The device features high RF power with dynamic power output to directly drive antennas at high efficiency, achieving large interaction distances even with small antenna sizes common in door handles. The device includes additional features, making it incomparable for low-power applications. It offers low-power card detection by performing a measurement of the I and Q channel, which represent the real and imaginary part of the antenna signal. It is designed to operate from a wide power supply range (from 2.7 to 5.5 V), ambient temperature range from -40 °C to +125 °C, and a wide peripheral I/O 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 1 qualification, the device is perfectly suited for automotive applications.
