Network Processor 32-Pin QFN T/R

The BlueNRG is a very low power Bluetooth low energy (BLE) single-mode network processor, compliant with Bluetooth specification v4.0. The BlueNRG can act as master or slave. The entire Bluetooth low energy stack runs on the embedded Cortex M0 core. The non-volatile Flash memory allows on-field stack upgrading. The BlueNRG allows applications to meet the tight advisable peak current requirements imposed by the use of standard coin cell batteries. The maximum peak current is only 10 mA at 1 dBm of output power. Ultra low-power sleep modes and very short transition times between operating modes allow very low average current consumption, resulting in longer battery life. The BlueNRG offers the option of interfacing with external microcontrollers using SPI transport layer.
