Description
General part information
ST25DV-DISCOVERY Series
The ST25R3920 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 ST25R3920 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 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.
