STM32W series of Wireless MCUs

The STM32W extends the STM32 family to the IEEE 802.15.4 wireless network domain bringing outstanding radio and low-power microcontroller performances.
  • Embedded 2.4 GHz IEEE 802.15.4 radio
  • Best-in-class code density, thanks to its ARM Cortex-M3 core
  • Low-power architecture
  • Open platform with extra resources for application integration:
    • Configurable I/Os, ADC, timers, SPI, UART
    • Main software libraries: RF4CE, IEEE 802.15.4 MAC, ZigBee-PRO, 6LoWPAN and more.
With a configurable total link budget up to 109 dB and the efficiency of the ARM Cortex-M3 core, the STM32W is a perfect fit for the wireless sensor network market.

The STM32W series includes devices with 64 to 256 KFlash, up to 16 KRam and is available in VFQFN40, UFQFN48 and VFQFN48 packages.

STM32W is Open Flexible Reconfigurable Platform

The kits demonstrate how effectively the STM32W108xx can be used in real IEEE 802.12.4 applications.
They are suitable for different types of wireless network scenarios such as:
  • Mesh networks (based on the ZigBee PRO protocol stack) typically used in home automation and smart energy applications
  • IPv6 over low power wireless Personal Area Networks
  • Remote control and target networks (based on the ZigBee RF4CE protocol stack) used for driving consumer devices such as TVs, set-top boxes, etc.
  • Point to point networks (based on a simplified MAC library) used to address a basic IEEE 802.15.4 communication. This configuration enables customers to develop any protocol stack of their choice
The STM32W-SK (also called STM32W108B-SK) and STM32W-EXT starter and extension kits are easy to use tools for the STM32W108xx microcontrollers. This family of microcontrollers integrates a 32-bit ARMŽ Cortex™-M3 microprocessor and a 2.4 GHz, IEEE 802.15.4-compliant transceiver. The kits demonstrate how effectively the STM32W108xx can be used in real IEEE 802.15.4 applications.
The STM32W108xx kits provide demonstration applications and documentation which serve as a reference for creating your own applications and re-programming the STM32W108xx microcontroller. You can run the STM32W108xx kits in several ways (building mesh networks, remote control/target and point-to-point applications), using the dedicated software libraries (ZigBee PRO, ZigBee RF4CE, and Simplified MAC), as well as a third-party IDE and C compiler (IAR).Moreover, the STM32W108xx kits provide a set of HAL APIs which allow you to use the kit platform capabilities such as LEDs and serial communication channels (virtual COM through USB).
