ST25R3916B-AQWT

ST25R3916 is high performance NFC universal device supporting NFC initiator, NFC target, NFC reader and NFC card emulation modes when applicable. Being fully compliant with EMVCo 3.0 analogue and digital, this NFC IC is optimized for POS terminal applications and enables the fastest EMVCo 3.0 certification cycles possible, even under harsh conditions with antenna around noisy LCD displays. The ST25R3916 includes an advanced analogue front end (AFE) and a highly integrated data framing system for ISO 18092 passive and active initiator, ISO 18092 passive and active target, NFC-A/B (ISO 14443A/B) reader including higher bit rates, NFC-F (FeliCa™) reader, NFC-V (ISO 15693) reader up to 53Kbps, and NFC-A / NFC-F card emulation. The ST25R3916 feature high RF output power to directly drive antennas at high efficiency. Include additional features, making it incomparable for low power applications. Suitable for a wide range of NFC and HF RFID applications.
