STMicroelectronics ST25R3914

The ST25R3914/5 are highly integrated NFC initiators / HF reader ICs for automotive applications, AEC-Q100 grade 1 qualified, including the analog front end (AFE) and a highly integrated data framing system for ISO 18092 (NFCIP-1) initiator, ISO 18092 (NFCIP-1) active target, ISO 14443A and B reader (including high bit rates), ISO 15693 reader and FeliCa™ reader. The ST25R3914/5 are positioned perfectly for the infrastructure side of the NFC system, where users need optimal RF performance and flexibility combined with low power. The ST25R3914/5 are alone in the domain of HF reader ICs as they contain two differential low impedance (1 Ohm) antenna drivers.
