Cloud-Compatible Wi-Fi Modules
The SPWF04 Cloud-compatible Wi-Fi module from STMicroelectronics is set to accelerate development of all kinds of IoT and M2M devices. The module provides advanced Internet-security and application protocols, and features a microcontroller capable of supporting operation in standalone or serial-to-Wi-Fi modes.

The SPWF04 Wi-Fi module integrates an Arm® Cortex®-M4 STM32 microcontroller with a rich set of multi-functional GPIOs and with 2 MB on-chip Flash and 256 Kbyte RAM for generous code and data storage. Further extra features include a hardware cryptographic accelerator and an SPI port for faster host communications. In addition, the new MicroPython scripting engine dramatically simplifies development of custom applications to run directly on the module in standalone mode. Host interactions can use AT commands via a UART, compatible with the previous generation of Wi-Fi modules, or equivalent proprietary protocol over SPI.

Features
  • 2.4 GHz IEEE 802.11 b/g/n transceiver
  • Web server supporting SSI
  • Open, WEP, WPA2 PSK, WPA2 Enterprise
  • WPS for station
  • Integrated TCP/IP protocol stack
    • 8 simultaneous TCP or UDP clients and 2 socket servers (supporting up to 8 clients each)
    • Secured socket and upper layers (i.e. HTTPS) supporting up to TLS 1.2, including X.509 Certificates, AES (128, 256), hash (MD5, SHA-1, SHA-256, SHA-384) and public key algorithms for key exchange (RSA, DH, ECDH) and digital signature (RSA, ECDSA).
  • System modes: Station, IBSS, and miniAP (supporting up to 5 Stations)
  • miniAP easily provisioned (SSID, PWD)
  • Fast Wi-Fi re-association after reset
  • Secure Firmware and FileSystem updates Over the Air (OTA)
  • High performance STM32F439
    • Arm Cortex-M4
    • 256 KB SRAM
    • 2 MB embedded high-speed Flash memory
    • 1 MB Flash memory for user storage, extendable via SD/MMC interface or external SPI Flash
