Data sheet:

The BlueNRG-2 is a very low-power Bluetooth® LE single-mode system-on-chip, compliant with Bluetooth specifications.


The BlueNRG-2 extends the features of the award-winning BlueNRG network processor, enabling the usage of the embedded Cortex® M0 to run the user application code.


The BlueNRG-2 includes 256 KB of programming flash memory, 24 KB of static RAM memory with retention (two 12 KB banks) and SPI, UART, I²C standard communication interface peripherals. It also features multifunction timers, watchdog, RTC, and DMA controller.


An ADC is available to interface with analog sensors, and to read the measurement of the integrated battery voltage sensor. A digital filter is available to process a PDM stream.


The BlueNRG-2 offers the same excellent RF performance of the BlueNRG radio, and the integrated high efficiency DC-DC converter keeps the same ultralow power characteristics, but the BlueNRG-2 improves the BlueNRG sleep mode current consumption allowing a further increase in the battery lifetime of the applications.
