STMicroelectronics has introduced the pre-programmed, ready for connection BLUENRG-2N Bluetooth 5.0 certified network processor. The new device has a very low power consumption, increased data throughput, and enhanced privacy and security.

The Data Length Extension of the BlueNRG-2N accelerates over-the-air (OTA) firmware updates by up to 2.5 times and raises the data transfers to 700kbit/s. By using the Bluetooth LE Privacy 1.2 the address of the device changes frequently, this prevents unwanted tracking with minimal impact on system power consumption.

By using the BlueNRG-2N, designers of smart medical wearables, PC peripherals, remote controls, lighting, industrial and home automation can optimize their choice of a microcontroller (MCU) to meet specific model requirements.

The BlueNRG-2N is designed with an Arm Cortex-M0 MCU to host the main application and Bluetooth connectivity on the same device. Developers working with BlueNRG chips can take advantage of the powerful and user-friendly STM32 online development environment (ODE), which includes the STM32CubeMX GUI plugin, to kick-start their projects.


Feature of BLUENRG-2N Network Processor

  • Sleep current consumption down to 900 nA
  • TX current consumption 6.8 mA (@ -2 dBm, 3.0 V)
  • RX current consumption 6.2 mA (@ sensitivity level, 3.0 V)
  • Up to +8 dBm programmable output power level (@ antenna connector)
  • Excellent RF link budget (up to 96 dB)


Note: More technical information can be found in the BLUENTG-2N datasheet linked at the bottom of this page and on the BLUENRG-2N Network Processor product page.
