The optimized and ultra-low power radio front-end combined with an excellent RF link and efficient power management architecture will extend battery life from months to years, making ST’s solution ideal for applications including lighting, smart home, beacons, fitness trackers, insulin pumps, hearing aids, or any energy-sensitive application.

A Bluetooth chip with a quick firmware upgrade

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

Several of our Bluetooth Low Energy 5.3 devices support proprietary as well as 802.15.4 protocols in concurrency mode.

Equipped with an on-board antenna, crystal oscillator and RF balun, ST’s Bluetooth Low Energy 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 applications.

STM32 Bluetooth Low Energy

Bluetooth LE 5.2 certified SoC enables extended range connectivity in lightweight applications

The BlueNRG-LP Programmable Bluetooth® LE 5.2 Wireless SoC supports advanced BLE features including long-range mode (Coded PHY), 2 Mbps transfers, Low Energy power control and advertisement extensions. Both radio and SoC architectures, including the flexible I/O peripherals, are highly optimized to achieve the lowest power consumption while offering uncompromised RF performance and a stunning 112 dB dynamic range for robust and reliable wireless connectivity.

Nicely tailored for lightweight applications, the SoC runs on the widely adopted Arm Cortex®-M0+ core, Arm’s most energy efficient processor, that processes user code in the embedded memories (25 Kbytes of Flash memory and 64 Kbytes of RAM) at a very low 14 µA/MHz and up to 64 MHz.

Developers can easily jump start their designs and debug prototypes thanks to the WiSE-Studio Eclipse IDE (STSW-WISE-STUDIO), our free GCC-based toolchain, and our BlueNRG-LP software development kit (STSW-BNRGLP-DK).

Designed to simplify evaluation cycles, the BlueNRG-LP evaluation board (STEVAL-IDB011V1) with onboard sensors and expansion connectors to further ease the start of new designs and shorten development time.
