Ready for Design
The MN54LM-20B is an advanced wireless module based on the nRF54LM20B System-on-Chip (SoC). As the most capable member of the nRF54L Series featuring high memory and an integrated Neural Processing Unit (NPU), the module is designed to meet demanding requirements for memory, edge AI processing performance, and ultra-low power consumption in advanced connected devices.
Core Processing, NPU, and Memory
-
Integrates a 128 MHz Arm® Cortex®-M33 application processor.
-
Features an integrated Axon NPU (Neural Processing Unit), delivering powerful hardware acceleration for edge AI workloads such as sound classification, keyword spotting, and anomaly detection with up to 15x higher efficiency and speed compared to CPU execution.
-
Features a built-in 128 MHz RISC-V co-processor to handle real-time or low-level custom protocols.
-
Equipped with 2 MB Non-Volatile Memory (NVM) and 512 KB RAM—the largest memory option in the nRF54L Series—sufficient to run complex applications, edge AI models, and concurrent wireless protocol stacks (such as Matter, Bluetooth Mesh, and Thread) without external memory.
Wireless Communication and RF Technology
-
Utilizes Nordic's fourth-generation ultra-low-power 2.4 GHz multiprotocol radio.
-
Supports Bluetooth LE (including Channel Sounding introduced in Bluetooth 6.0), Thread, Matter, Zigbee, Bluetooth Mesh, and proprietary 2.4 GHz protocols with data rates up to 4 Mbps.
Advanced Process and Power Efficiency
