The nRF54L Series offers SoCs that combine an efficient MCU with ultra-low-power wireless connectivity.

The nRF54LM20B provides the largest memory option in the series, with 2 MB NVM and 512 KB RAM.

It features an extended set of peripherals, high-speed USB, and is available with up to 66 GPIOs.

The nRF54LM20B also includes an integrated Axon NPU, increasing the speed and efficiency of on-device AI inferencing up to 15x compared to using the CPU for the same task.

nRF54LM20B supports Bluetooth LE, Matter, Thread, Zigbee, and 2.4 GHz proprietary protocols with data rates up to 4 Mbps for low-latency applications.

It also supports Bluetooth Channel Sounding, Bluetooth Mesh, and Wi-Fi with nRF70 Series companion ICs.
