Offering ultra-low power consumption together with an excellent RF link budget for robust and reliable connectivity, our portfolio of Bluetooth Low Energy solutions includes both network and application processors in QFN-32, QFN-48 or WLCSP-34 miniaturized packages.

The optimized radio front-end and the efficient power management architecture will extend battery life from months to years. The on-chip non-volatile memory enables an easy and quick firmware upgrade, including in-the-field over-the-air (OTA) upgradability.

Equipped with an on-board antenna, crystal and RF balun, ST BLE modules offer a proven, robust solution that ensures a quick time-to-market. They come with the embedded Bluetooth 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 wireless connectivity technology into a wide variety of application segments.

Bluetooth Low Energy

Next-generation Bluetooth low energy chip: boosts the boom of connected smart things

The BlueNRG-2 is the new generation of the Bluetooth® Low Energy (BLE) system-on-chip, 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 BlueNRG-2 comes with a dedicated evaluation kit (STEVAL-IDB008V2, which includes the new integrated RF balun), a new software development kit (SDK) and a BlueNRG Navigator graphical user interface (GUI).

BlueNRG-1 System on Chip delivers low power consumption and radio-connection reliability

The BlueNRG-1 single-core SoC, based on a  32MHz 32-bit ARM® Cortex®-M0, enables you to forge Bluetooth Smart applications with prolonged battery lifetime, minimizing overall cost and time-to-market. Its compliancy with the BLE specification v4.2 and the embedded AES-128 and ECC-256 crypto engines enable top-notch security and privacy. The wide set of peripherals, easy code upgradability, the extended temperature range (up to 105 °C) and the premium +8 dBm output power represent a unique recipe for uncompromised performance. The innovative ultra-low-power design includes support for fast wake-up and sleep transitions and unrivalled sub-1μA standby current. The device comes with a brand new SDK and a sensorized development board for quick application prototyping. The BlueNRG-1 comes in both QFN-32 or WLCSP-34 packages.
