STMicroelectronics has revealed its first Bluetooth Low Energy wireless system-on-chip (SoC). The BlueNRG-1 is optimised to satisfy high-volume opportunities in the Bluetooth Low Energy market.

Bluetooth Low Energy devices must ensure energy-efficient operation, including low power consumption in sleep and standby modes that are used frequently to maximise battery life. Strong radio performance is also needed to advertise availability and connect reliably. ST has designed the BlueNRG-1 programmable SoC with performance and power to satisfy these requirements.

The integrated radio transceiver is power efficient in the modes frequently used by devices such as beacons when setting up short-duration connections for exchanges like sharing offers with shoppers’ smartphones. The SoC’s ability to transition quickly between power-saving and active modes extends battery life from months to years. RF output power is boosted to +8 dBm to ensure clear communication for optimum efficiency, even in noisy environments.

A dedicated digital-microphone input simplifies voice-enabled applications, while 105°C maximum operating temperature makes the device suitable for smart lighting and automotive applications. Support for the latest Bluetooth Low Energy version 4.2 specification ensures privacy and security.
