STM32WBA Series

The STM32WBA MCU series brings designers performance, efficiency, and flexibility. It embeds large memory to sustain both applications and connectivity activities, coming with up to 1 Mbytes of flash memory and 128 Kbytes of RAM. A smart set of peripherals like ADC, touch sensing, times, make this product a self-sufficient application wireless MCU.

  • High data rate to ensure fast and reliable data transfer
  • Multi-protocol flexibility (Bluetooth® Low Energy 5.4, IEEE 802.15.4 communication protocols, Zigbee®, Thread and Matter)
  • Long range capability to enlarge communication range
  • High output power to increase communication range thanks to +10 dBm of output power
  • Low-power messaging capability to extend battery lifetime

Based on the Arm® Cortex®-M33 core running at 100 MHz with TrustZone® technology, the STM32WBA series provides a high level of security, protecting data, IPs, and preventing hacks or device cloning.
