  • The ST25R3916/7 are high performance NFC universal devices supporting NFC initiator, NFC target, NFC reader and NFC card emulation modes when applicable.

    Being fully compliant with EMVCo 3.0 analog 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.
    Both devices include an advanced analog 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 53 kbps, and NFC-A / NFC-F card emulation.
    Special stream and transparent modes of the AFE and framing system can be used to implement other custom protocols in reader or card emulation mode.
    The ST25R3916/7 feature high RF output power to directly drive antennas at high efficiency.
    The ST25R3916/7 include additional features, making them incomparable for low power applications. They contain a low power capacitive sensor to detect the presence of a card without switching on the reader field. Additionally, the presence of a card can be detected by performing a measurement of the amplitude or phase of the antenna signal. They also contain a low power RC oscillator and wake-up timer to automatically wake-up the ST25R3916/7 after a selected time period and check for a presence of a tag using one or more techniques of low power detection of card presence (capacitive, phase or amplitude).
    The ST25R3916/7 are 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).
    Due to this combination of high RF output power, low power modes and wide supply range these devices are perfectly suited for infrastructure NFC applications.
