    Product Details

    The STMicroelectronics Automotive high performance NFC reader for CCC digital key and car center console 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 ST25R3920B 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.

    Dynamic power output (DPO) controls the field strength to stay within given limits
    Active wave shaping (AWS) reduces over-and under-shoots
    Noise suppression receiver (NSR) allows reception in noisy environment
    Automatic antenna tuning (AAT) via variable capacitor
    Integrated EMVCo® 3.1a compliant EMD handling
    Automatic gain control and squelch feature to maximize SNR
    Low power NFC active and passive target modes
    Adjustable ASK modulation depth, from 0 to 82%
    Integrated regulators to boost system PSRR
    AM/PM and I/Q demodulator with baseband channel summation or automatic channel selection
    Possibility to drive two independent single ended antennas
    Measurement of antenna voltage amplitude and phase, RSSI, on-chip supply and regulated voltages

    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 is used to implement other custom protocols in reader or card emulation modes.
