With up to +8dBm programmable RF output power and
Equipped with -104dBm RF reception sensitivity, supports Bluetooth Mesh


On the 23rd, STMicroelectronics launched 'BlueNRG-LP', a Bluetooth LE (Bluetooth® Low Energy) SoC (System-on-Chip) incorporating the latest Bluetooth features.

BlueNRG-LP is optimized with power consumption of 3.4mA when receiving, 4.3mA when transmitting, and less than 500nA when waiting for a wake-up event, which can reduce the required battery size by half and extend operating time for most applications.

ST's third-generation Bluetooth SoC, BlueNRG-LP, is a Bluetooth LE 5.2 certified SoC that supports simultaneous connections to up to 128 nodes, enabling monitoring of various connected devices and smooth control with low latency.

In addition, it features RF output power that can be programmed up to +8dBm and RF reception sensitivity up to -104dBm. Communication range can be easily extended as part of the ST BlueNRG software and hardware ecosystem that supports Bluetooth LE Mesh.

In addition, it supports Bluetooth Long Range Mode, which uses Forward Error Connection (FEC) and Coded PHY to extend the wireless communication range up to several hundred meters and increase stability, as well as providing fast and efficient connections through Generic Attribute (GATT) caching.

◇ Supports various communication protocols and has built-in security features

BlueNRG-LP comes with ST's third-generation Bluetooth LE protocol stack, which is Core Specification 5.2 certified.

The stack is provided as a free library that can be linked independently of compilers supported by various IDEs (Integrated Development Environments). It also supports features such as extended advertising and scanning, high duty cycle connectionless advertising, extended packet length, and throughput of 2 Mbit/s.

It supports L2CAP CoC (Connection-Oriented Channel), which facilitates large-scale bidirectional data transmission, multi-role simultaneous connectivity, and CSA #2 (Channel Selection Algorithm #2), which ensures stable connections even in noisy environments such as home, building, or industrial networks.

The enhanced security mechanisms included in the integrated Arm Cortex-M0+ MCU consist of a secure bootloader, read protection across 256KB of embedded flash, a 48-bit unique ID and customer key store, a True Random-Number Generator (TRNG), a hardware Public-Key Accelerator (PKA), and a 128-bit AES cryptographic coprocessor.

This processing unit executes code at a maximum of 64 MHz and has a power consumption of 18 µA/MHz. In addition, it features an industry-standard digital interface, a multi-channel 12-bit ADC, an analog microphone interface with a programmable gain amplifier, user and system timers and a watchdog, and up to 31 5V-allowed user-programmable I/O pins.

The BlueNRG-LP SoC integrates an embedded RF balun and DC/DC converter, as well as capacitors supporting a High-Speed External (HSE) oscillator and an internal low-speed ring oscillator, minimizing component costs and simplifying circuit design.

Supported by ST’s 10-year industrial product supply warranty and ensuring long-term component availability, the BlueNRG-LP SoC is currently being produced in a 6mm×6mm QFN48 package and is priced at less than $1 for bulk purchases.
