Nordic Semiconductor releases nRF54LM20B SoC

Nordic Semiconductor expanded its ultra-low-power edge Artificial Intelligence (AI) portfolio and released the nRF54LM20B System-on-Chip with an integrated Neural Processing Unit (NPU), a change the company framed as making energy-efficient on-device intelligence available to developers and battery-powered devices.

The company said the NPU-enabled nRF54LM20B provided the performance required for real-time intelligence in battery-powered wearables, smart home and audio devices, industrial and medical sensors, and trackers, supporting activity detection, natural sound and presence response, instant anomaly identification, and movement interpretation without cloud processing.

Nordic reported that the nRF54LM20B's integrated NPU accelerated TensorFlow Lite–class models up to 15 times faster and with lower energy consumption than execution on the Arm Cortex Central Processing Unit (CPU), and that it delivered up to seven times higher performance and eight times better energy efficiency versus the closest competing edge AI solution.

The company said it had expanded developer workflows and tool support, including an online model generation tool named Nordic Edge AI Lab with streamlined model creation and optimization, wake-word creation from a single text input, and options to generate models for accelerated inference on the NPU or efficient execution on the CPU; the nRF54LM20 DK was made available through Nordic's distribution partners and SoC samples were offered via Nordic Sales.

“This new generation of edge AI-enabled capabilities fundamentally transforms what small, battery-powered devices can perceive and interpret in the real world,” “By bringing powerful intelligence directly onto the device – without compromising power efficiency, latency, or system complexity – we are enabling an entirely new class of products that are significantly smarter, more responsive, and dramatically more energy-efficient than anything previously possible.” said Øyvind Strøm, EVP Short-Range at Nordic Semiconductor.

Nordic said volume production was expected to begin in Q2 2026.
