STM32 W series Wireless MCUs, IEEE 802.15.4

The STM32 family is expanding to the wireless network domain bringing outstanding radio and low-power microcontroller performances. 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. Compliant with the IEEE 802.15.4 radio standard, this open and flexible platform supports the most popular protocol stacks such as RF4CE, ZigBee-PRO, 6LoWPAN and more.

  • STM32W based on Cortex-M3 running up to 24 MHz
  • 2.4 GHz IEEE 802.15.4 transceiver and lower MAC with excellent RF performance:
    • Rx sensibility up to -100 dBm
    • Output power configurable up to +8 dBm
  • Low-power-mode consumption (0.4 μA with RAM retention)
