ST25R3920B-AQWT Automotive NFC Reader IC For Digital Key / Car Center Console CCC

ST25R3920B-AQWT Automotive high performance NFC reader for CCC digital key and car center console

Description of ST25R3920B-AQWT
The ST25R3920B-AQWT is an automotive grade high performance NFC universal device supporting NFC initiator, NFC target, NFC reader and NFC card emulation modes.
The ST25R3920B-AQWT 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.
The ST25R3920B-AQWT 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).
