Sales Briefcase
  • The SPWF01SA and the SPWF01SC intelligent Wi-Fi modules represent a plug-and-play and standalone 802.11 b/g/n solution for easy integration of wireless internet connectivity features into existing or new products.

    Configured around a single-chip 802.11 transceiver with integrated PA and comprehensive power management subsystem, and an STM32 microcontroller with an extensive GPIO suite, the modules also incorporate timing clocks and voltage regulators. Two different options exist based on the integrated Flash memory. The SPWF01Sx.1y orderable parts integrate 1.5 MB of Flash, while the SPWF01Sx.2y orderable parts integrate 512 kB of Flash.
    The module is available either configured with an embedded micro 2.45 GHz highly-efficient ISM band antenna (SPWF01SA), or with an u.fl connector for external antenna connection (SPWF01SC).
    With low power consumption and ultra-compact (2.7 x 1.5 cm) footprint, the modules are ideal for fixed and mobile wireless applications, as well as challenging battery-operated applications.
    The SPWF01Sx parts are released with an integrated full featured TCP/IP protocol stack with added web server and additional application service capabilities, such as REST API for accessing files on servers in the cloud and support for dynamic web pages with CGI/SSI functions to easily interact with the module and the host processor over the air.
    For secure end-to-end communication with the cloud, an SSL/TLS stack is embedded in every module with no licensing charge. See AN4683 for details.
    The SW package also includes an AT command layer interface for user-friendly access to the stack functionalities via the UART serial port. For details, see UM1695.
    It is always possible to upgrade the module firmware via UART and Over-The-Air (FOTA).
    Out of the 1 MB extended Flash available on the SPWF01Sx.1y module, 512 kB of the Flash is dedicated to FW upgrade and the other 512 kB is dedicated to host proprietary files, organized in a file system image, accessible through the integrated web server.
    FOTA is also possible with the SPWF01Sx.2y module, temporarily storing the FW in the external host Flash memory, if it exists.
    ST may update the FW provided with the modules at any time. ST recommends that users regularly check for documentation and the current FW version available at www.st.com/wifimodules.
