Product Description
The EFR32BG26 Bluetooth SoCs are ideal for IoT wireless connectivity using Bluetooth Low Energy and Bluetooth mesh for smart home, lighting, and portable medical products. With key features like high-performance 2.4 GHz RF, low current consumption, an AI/ML hardware accelerator, and Secure Vault™, IoT device makers can create the smart, robust, and energy-efficient products that are secure from remote and local cyber-attacks. An ARM Cortex®-M33 running up to 78 MHz and up to 2048 kB of Flash and 256 kB of RAM provides resources for demanding applications while leaving room for future growth. Target applications include gateways/hubs, sensors, switches, door locks, smart plugs, LED lighting, luminaires, blood glucose meters and pulse oximeters.EFR32BG26 Common Specs
