A wireless dual-core brain
The STM32WB series is a
dual-core, multi-protocol and
ultra-low-power 2.4 GHz MCU
system-on-chip.
It supports Bluetooth
®
LE 5.2 as
well as IEEE 802.15.4 protocols
(in Single and Concurrent
modes) covering a wide
spectrum of IoT application
needs.
Based on ST’s best-in-class,
ultra-low-power MCU with wide
peripheral set, the STM32WB
series reduces development
time, BOM cost, and extends
application battery life.
STM32WB inspires innovation.
Bluetooth
®
LE 5.2 & IEEE
802.15.4
The STM32WB SoC offers
multi-protocol stacks including
Bluetooth
®
5.2, OpenThread,
Zigbee 3.0, proprietary protocols
and concurrent mode, for best
in-class RF performance.
Dedicated core to radio activity
provides SW exibility and
better user experience.
IP Protection
STM32WB devices offer
device integrity and industrial
IP protection features to meet
manufacturers’ increasing
demand for brand protection.
Note* Features availability or caracteristics depend on STM32WB reference

STM32WB PORTFOLIO
HARDWARE TOOLS
This STM32 Nucleo pack is the most cost-effective way to
quickly get started developing STM32WB-based prototypes.
EMBEDDED SOFTWARE
The STM32CubeWB package includes the STM32Cube
hardware abstraction layer (HAL) and low-layer (LL)
APIs peripheral drivers, a consistent set of middleware
components (RTOS, USB, FatFS and STM32 touch
sensing), as well as Bluetooth
®
LE 5.2, OpenThread and
Zigbee 3.0 connectivity stacks. All embedded software
components come with a full set of examples running on
STMicroelectronics boards.
SOFTWARE TOOLS
STM32CubeMX
Enables faster development thanks to
its MCU pinout and clock congurator,
power consumption calculator and code
generation tools.
STM32CubeIDE
Is an Eclipse-based IDE which integrates
the features of the STM32CubeMX
conguration tool.
STM32CubeMonitor
Is a development tool dedicated to
wireless connectivity (STM32CubeMonRF)
which helps reduce time-to-market by
enabling radio testing and beaconing.
STM32CubeProg
Is an all-in-one software tool for
programming STM32 devices which can
be easily used to interact with the memory
of the STM32WB, including secure
programming of the RF stacks.
STM32WBx0 VALUE LINE
Extending our portfolio, the STM32WBx0 Value Line focuses
on the essentials and offers a feature-optimized solution
to help developers meet the design requirements of cost-
sensitive industrial and consumer IoT applications.
The STM32WB55 Nucleo pack is a useful tool to quickly get
you started with the STM32WBx0 microcontrollers.
Companion chip
STMicroelectronics’ integrated matching RF components are tailored for STM32WB packages :
MLPF-WB55-0xE3, QFN: x=0, WLCSP100 : x =2.
