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.
