BlueNRG-2 Bluetooth low energy wireless single chip related information [Copy link]

BlueNRG-2 is a single-chip SoC with ultra-low-power Bluetooth BLE that complies with Bluetooth standard specifications.

BlueNRG-2 expands ST's award-winning BlueNRG series of Bluetooth network processors, with a built-in Cortex M0 core that can run customer application code. It
also includes 256KB of program ROM, 24K RAM with retention function (divided into 2 blocks, 12KB each), and standard peripheral communication interfaces such as SPI, UART, and I2C. In addition, BlueNRG-2 is also equipped with many modules such as multi-function timer, watchdog, real-time clock and DMA controller. The
internal ADC module can be connected to external analog sensors and can also read the internal battery voltage sensor measurement value. A built-in digital filter can be used to process external PDM data streams.
BlueNRG-2 has the same excellent RF performance, and the built-in high-efficiency DC-DC converter has the same ultra-low power consumption characteristics, while improving the power consumption in sleep mode, which can further extend the battery life in practical applications.
