STMicroelectronics BlueNRG-1 BLE Wireless System-On-Chip

STMicroelectronics BlueNRG-1 Bluetooth Low Energy (BLE) Wireless System-On-Chip extends the features of the award-winning BlueNRG network processor. The SoC enables the usage of the embedded Cortex M0 for running user application code. The BlueNRG-1 have an extremely power-efficient integrated radio transceiver for modes frequently used by devices like beacons. Battery life can be extended by the BlueNRG-1's ability to transition quickly between power-saving and active modes. In addition, RF-output power is boosted to +8dBm to ensure clear and reliable communication for optimum efficiency, even in noisy environments.
