Nordic adds AI-assisted development to the nRF Connect SDK and nRF Cloud

Nordic Semiconductor has added AI-assisted development to its wireless IoT microcontroller, with workflows covering the full life cycle from the first prototype to a deployed fleet. Many developers copy/paste information from LLMs trained on generic data. However, Nordic’s AI solution is specifically trained on the nRF Connect SDK documentation and nRF Cloud data and integrates with a developer’s favorite IDE. It also connects to Claude Code, Cursor, GitHub Copilot, or any other LLM at a much lower token cost thanks to the specialized model. The company says it’s based on an implementation of the Model Context Protocol (MCP), where the Nordic MCP servers give AI assistants access to validated sources from Nordic, including SDK documentation, API references, device configurations, and the customer’s field data from nRF Cloud. Highlights of Nordic’s AI-assisted development Connected to nRF Connect SDK documentation and nRF Cloud data Integrates with AI assistants such as Claude Code, […]

Nordic Semi nRF54LM20B wireless SoC integrates 128 MHz Axon NPU for Edge AI workloads

Nordic Semi nRF54ML20B Arm Cortex-M33 wireless SoC is the first nRF54L microcontroller to integrate the ultra-efficient Axon Neural Processing Unit (NPU) for edge AI workloads. The NPU is said to deliver up to 7 times faster performance and up to 8 times higher energy efficiency versus (unnamed) competing wireless solutions for tasks such as sound classification, keyword spotting, and image-based detection. The Axon NPU is also about 15x faster compared to using the Cortex-M33 CPU for the same task.
