STM32WB0 MCU Series: The Future of Bluetooth Low Energy 5.3 Wireless Connectivity

The STM32WB0 microcontroller series allows for reliable wireless connectivity through a compact and energy efficient design.

Certified to the Bluetooth Low Energy 5.3 standard, the STM32WB0 provides an outstanding wireless radio and low-power capabilities that make it well-suited for wireless applications where cost and energy efficiency are priorities.

What the STM32WB0 offers

The STM32WB0 offers high performance wireless connectivity through its best-in-class radio, providing robust and stable connections. It features an Arm Cortex-M0+ core that operates at 64 MHz along with 512 KB of flash memory and 64 KB of RAM.

Wireless performance is certified and modular stacks developed by ST are robust and well-maintained. High data transfer speeds of up to 2 Mbps ensure fast and reliable transmission of data.

The state-of-the-art radio delivers excellent sensitivity of up to -104 dBm and output power up to +8 dBm, along with direction finding support for accurate Bluetooth location solutions.

Battery life is extended for IoT devices through the radio’s high efficiency of 3.9 mA for transmission and 3.2 mA for reception at peak power, along with power control options. The Cortex-M0+ core consumes only 15.5 μA/MHz.

Costs are lowered through an affordable price point. Integration is maximized through small packages including components like balun and capacitor-less 32 MHz crystals, reducing bills of materials and simplifying circuitry to allow for 2-layer PCBs.

Development is streamlined using an extensive ecosystem that provides hardware designs, radio IPs, Bluetooth stacks, software, tools and resources.

Product types

The STM32WB09 microcontroller line, as the initial product in the STM32WB0 series, integrates ST’s advanced 2.4 GHz radio IP to deliver outstanding wireless performance. The STM32WB09 line contains a highly efficient switched-mode power supply (SMPS) step-down converter that enables unrivaled battery life.

Owing to its 512 KB flash memory, 64 KB RAM, along with intelligent peripherals such as the ADC and timers, the STM32WB09 can address basic to more sophisticated Bluetooth Low Energy applications in industrial and consumer markets. This wide range of capabilities makes it suitable for entry-level to complex wireless designs.
