Get Started

Our Bluetooth® Low Energy portfolio is now boosted with Bluetooth LE 5.0 and Bluetooth mesh connectivity stack. The wide portfolio includes optimized network and application processors, as well as an all-in-one solution combining both in a single-die product. Up to 7 packages are available (from QFN32, LGA86 to WLCSP100) to fit any footprint or feature requirements.

The optimized, ultra-low power radio front-end and the excellent RF link, combined with the efficient power management architecture, extend device battery life from months to years. This makes ST’s solutions ideal for applications such as lighting, smart homes, beacons, fitness trackers, insulin pumps, hearing aids, and many more energy-sensitive applications..

Quick firmware upgrade

The on-chip non-volatile memory (NVM) enables quick and easy firmware upgrade, including in-the-field over-the-air (OTA) upgrade with authentication and encryption firmware if needed.

Several of our Bluetooth LE 5.0 devices support proprietary and 802.15.4 protocols in concurrent mode.


Equipped with an on-board antenna, crystal and RF balun, ST BLE modules offer a proven, robust solution that ensures quick time to market. Our modules come with the embedded Bluetooth LE stack to provide a certified Bluetooth Qualification Expert (BQE) solution that is also fully RED, IC and FCC-approved, thus ensuring rapid integration into the final application and providing an easy-to-use solution.



Our Bluetooth Low Energy ICs and modules are supported by an extensive set of evaluation boards, software development kits, application notes and design guidelines – thus facilitating the adoption of Bluetooth LE wireless connectivity technology into a wide variety of application segments.



New-generation Bluetooth 5.0 chip: boosts the boom of connected smart things

ST offers the widest Bluetooth 5.0 portfolio on the market with 2 new system-on-chip series.

The BlueNRG-2 is the new generation of the Bluetooth® Low Energy (BLE) system-on-chip single core, with a generous integrated 256-Kbyte Flash memory, scalable GPIO pins and up to 105 °C operating temperature. The BlueNRG-2 comes in both QFN-32 and the new QFN48 package that offers 26 GPIOs and more flexibility to add sensors and unleash Bluetooth Low Energy connectivity. Moreover, the latest version of the BLE stack adds state-of-the-art security and privacy along with faster data transfers. The embedded Arm® Cortex®-M0 processor and the extremely power-efficient architecture extends battery life while the high-power strength of the radio ensures robust and reliable wireless communication.

Bluetooth 5.0 qualification ensures interoperability with the latest smartphones and tablets as well as backward compatibility with older products.

The STM32WB is the latest STMicroelectronics’s solution offering a certified Bluetooth 5.0 combined with IEEE 802.15.4. The STM32WB series is a dual core system-on-chip with an arm cortex-M0+ core handling the radio protocol stack as well as the Customer Key Storage IP (CKS) that enable secure firmware and/or radio stack update. The second core, an arm cortex-M4, is fully dedicated to the user application. On top of the various connectivity peripherals and rich analog set the STM32WB offers a wide portfolio from 256KB to 1MB of embedded flash and 128KB to 256KB of SRAM. The series supports up to 105°C ambient temperature and is available on QFN48, QFN68 and WLCSP100 package.
