STMicroelectronics introduce Cloud-Compatible Wi-Fi Module which simplifies and secures IoT and M2M applications

Date Published : 01/04/2017 Share with:

The SPWF04 Wi-Fi module integrates an ARM® Cortex®-M4 STM32 microcontroller with a rich set of multi-functional GPIOs and with 2MB on-chip Flash and 256Kbyte 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.

Support for strong internet-security protocols includes WPA2-Enterprise, which enables enhanced authentication and access control in large networks, and Wireless Protected Setup (WPS) that helps safely connect devices like printers or embedded systems. There is also support for advanced HTTPS and encryption protocols including Transport Layer Security (TLS), as well as Secured Over-The-Air (OTA) updates for applying software, firmware, or Flash file-system upgrades in the field via the Wi-Fi connection.
