  • The ST21NFCD is a single NFC controller IC designed for integration in mobile devices and NFC compliant products. It includes NFC functions in the three operating modes: Card Emulation, Reader/Writer and Peer to Peer communication.

    This product is based on an advanced ARM Cortex-M3 32-bit microcontroller running at 28 MHz.
    All internal operations are synchronized by a Clock Generator module.
    Two clock source options are available: using an external Quartz or using an external reference clock (in order to reduce the number of external components).
    Thanks to an enhanced power switch system, the ST21NFCD manages the power supply of the device and its associated Secure Elements.
    The ST21NFCD supports NCI 2.0.
    In order to meet environmental requirements, ST offers these devices in different grades of ECOPACK® packages, depending on their level of environmental compliance. ECOPACK® specifications, grade definitions and product status are available at: www.st.com. ECOPACK® is an ST trademark.
