EDI CON CHINA 2020 celebrates electronic design innovation, bringing together RF, microwave, EMC/EMI, and high-speed digital design engineers and system integrators for networking, training, and learning opportunities.

 

The BlueNRG-LP is an ultra-low power programmable Bluetooth® Low Energy wireless SoC solution. It embeds STMicroelectronics’s state-of-art 2.4 GHz RF radio IPs combining unparalleled performance with extremely long-battery lifetime. It is compliant with Bluetooth® Low Energy SIG core specification version 5.2 addressing point-to-point connectivity and Bluetooth Mesh networking and allows large-scale device networks to be established in a reliable way. The BlueNRG-LP is also suitable for 2.4 GHz proprietary radio wireless communication to address ultra-low latency applications.

ST is launching today the BlueNRG-LP, the first Bluetooth Low Energy SoC to support 128 concurrent connections. It is also our first device to receive the Bluetooth Low Energy 5.2 certification. The BlueNRG-LP supports features such as Long Range, 2 Mbps transfers, and advertisement extensions, to name a few. Additionally, it draws from previous architectures to offer the broadest dynamic range ever on an ST Bluetooth chip. To achieve such a level of performance and optimization, our teams focused on the SoC’s radio and the microcontroller. The latter is now a Cortex-M0+ running at 64 MHz and it uses 64 KB of RAM. Comparatively, the BlueNRG-1 and BlueNRG-2 rely on a Cortex-M0 at 32 MHz and 24 KB of RAM. The new device also has a one-time programmable memory area for security purposes.
