BlueNRG-2 supports the Bluetooth 5.0 certification, which allows enhanced security with LE Secure Connections, power-efficient privacy with Link Layer Privacy 1.2, and up to 2.6-times higher throughput with LE Data Length Extension. The SoC contains an Arm Cortex-M0 core operating at up to 32 MHz to handle the Bluetooth stack and application processing, and integrates new features including a 32 kHz ring oscillator, 24-KB RAM and 256-KB Flash program memory. Reduced standby power is a further advantage, drawing just 0.9 µA in sleep mode with active Bluetooth stack and full RAM retention.
The BlueNRG-M2SA module combines in a compact 13.5- x 11.5-mm form factor the BlueNRG-2 SoC with an efficient ceramic antenna, RF balun circuit, and 32 kHz crystal oscillator and SMPS inductor to further reduce power consumption. Using this module greatly reduces engineering costs and enables designers to create wireless devices with minimal radio-frequency engineering expertise. BlueNRG-M2SA is qualified as a Bluetooth End Product, which relieves customers of additional testing to complete their own product qualification. The modules are also pre-certified according to US FCC, Canadian IC, European RED, Japan TYPE radio-equipment regulations and will also meet China SRCC requirements when those are finalized.
