The nRF54LM20B is an ultra-low-power wireless System-on-Chip for battery-powered connected products that require secure connectivity and on-device intelligence. It combines a 128 MHz Arm Cortex-M33 application processor, a 128 MHz RISC-V coprocessor, Nordic’s proprietary 128 MHz Axon Neural Processing Unit, 2 MB non-volatile memory, 512 KB RAM, embedded security, peripherals, and a multiprotocol 2.4 GHz radio in one device. The integrated architecture supports TensorFlow Lite inference on the NPU and compact Neuton models on the CPU, which can run at the same time, plus wireless operation across Bluetooth Low Energy, Bluetooth Channel Sounding, Bluetooth Mesh, Matter, Thread, Zigbee, Aliro, and proprietary 2.4 GHz protocols. It suits earbuds, fitness bands and rings, voice-controlled remotes and speakers, smart-home sensors, medical and industrial sensors, and asset trackers, where local inference improves responsiveness, privacy, battery life, and product size.
