  • Bluetooth low energy single mode system-on-chip
  • Bluetooth 4.2 compliant, LE Data Packet Length Extension
  • Operating temperature range: -40 °C to 105 °C
  • Cortex-M0 32-bit core with 256 KB Flash

The BlueNRG-2 is a very low power Bluetooth low energy (BLE) single-mode system-on-chip, compliant with Bluetooth specification V4.2. It 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 for interfacing with analog sensors, and for reading the measurement of the integrated battery monitor. A digital filter is available for processing a PDM stream.
