New SoC Improves Sleep Mode Current Consumption and Battery Life in Devices

02 October 2017

Mouser Electronics is now stocking the BlueNRG-2 system-on-chip (SoC) from STMicroelectronics (ST). The BlueNRG-2 SoC is a power-efficient programmable processor with ultra-low-power features, high RF signal strength and generous on-chip memory for Bluetooth® low energy software and application code. The BlueNRG-2 is a Bluetooth, 4.2-compliant and Bluetooth 5.0-certified. This ensures interoperability with the latest generation of smartphones and supports enhanced features, like state-of-the-art security, privacy and extended packet length for faster data transfer.


ST’s BlueNRG-2 wireless SoC offers the same RF performance as the BlueNRG radio and improves sleep mode current consumption for longer applications and battery lifetime. The SoC has a 32-bit Arm® Cortex®-M0 processor and a Bluetooth low energy radio for energy efficiency and radio performance. The BlueNRG-2 includes 256 kBytes of on-chip flash memory which allows designers to embed the Bluetooth low energy stack and the application code; 24 kBytes of static RAM with retention (in two 12-kBytes of static RAM with retention; and SPI, UART I²C standard communication interface peripherals.

The device benefits from an ultra-low-power design, including support for fast wake-up and sleep transitions and a standby current of 500 nA. The RF-output power is boosted to +8 dBm to ensure clear and reliable communication for optimum efficiency. The BlueNRG-2 SoC is compliant with a range of RF regulations, like ETSI EN 300 328, EN 300 440, FCC CFR47 Part 15 and ARIB STD-T66.

Along with this device, Mouser is offering the STEVAL-IDB008V1 evaluation platform that includes an onboard BlueNRG-2 SoC with an accelerometer, gyroscope, MEMS pressure and temperature sensor and debug connector. When used with the STSW-BLUENRG1-DK software development kit (SDK), the evaluation board’s three power options help engineers develop solutions for many applications.
