BLUENRG-232

The BlueNRG-2 is a very low power Bluetooth low energy (BLE) single-mode system-onchip, compliant with Bluetooth specification. The BlueNRG-2 extends the features of award-winning BlueNRG network processor, enabling the usage of the embedded Cortex M0 for running 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, I?C 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.
