The BlueNRG-2 system-on-chip (SoC) from STMicroelectronics (ST) is now being shipped by Mouser Electronics. 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.
It is Bluetooth 4.2-compliant and Bluetooth 5.0-certified, which ensures interoperability with the latest generation of smartphones, and supports enhanced features such as state-of-the-art security, privacy, and extended packet length for faster data transfer.
The wireless SoC offers the same RF performance as the BlueNRG radio, but improves sleep mode current consumption for longer application battery lifetime.
It features a 32-bit Arm Cortex-M0 processor and a Bluetooth low energy radio for energy efficiency and strong radio performance.
The device also includes 256kBytes of on-chip flash memory, allowing designers to embed both the Bluetooth low energy stack and the application code; 24kBytes of static RAM with retention (in two 12kByte banks); and SPI, UART, I2C standard communication interface peripherals.
An ultra-low-power design enables support for fast wake-up and sleep transitions, and a standby current of just 500nA.
In addition to the device's excellent link budget up to 96 dB, RF-output power is boosted to +8dBm to ensure clear and reliable communication for optimum efficiency, even in noisy environments.
The BlueNRG-2 SoC is compliant with a range of RF regulations, including ETSI EN 300 328, EN 300 440, FCC CFR47 Part 15, and ARIB STD-T66.
Mouser is also offering the STEVAL-IDB008V1 evaluation platform, which includes an onboard BlueNRG-2 SoC with an accelerometer, gyroscope, MEMS pressure and temperature sensor, and debug connector. Used in conjunction with the fully featured STSW-BLUENRG1-DK software development kit (SDK), the evaluation board’s three power options help engineers develop solutions for a wide range of applications, including wearables, retail beacons, keyless entry systems, smart remote controllers, asset trackers, and industrial and medical monitors.
