Nordic Semiconductor — nRF54L Series Wireless SoCs

The Nordic Semiconductor nRF54L Series of wireless SoCs offers a substantial boost in processing capability and power efficiency, providing for longer run-time and higher performance in battery-operated IoT devices.  

Based on a 128MHz Arm® Cortex®-M33 core, the nRF54L Series offers around twice the processing power of the earlier nRF52 with up to 50% lower power consumption. The new nRF54L 2.4GHz radio supports Bluetooth Low Energy protocol advanced features including Bluetooth Channel Sounding and Bluetooth Mesh. The SoCs also implement Thread, Zigbee, and Matter connectivity for use in smart home networks. 

The entry-level nRF54L05 is optimized for applications such as simple sensors, beacons and asset trackers. The mid-range nRF54L10 and nRF54L15 add more memory to accommodate wearables, medical devices and industrial sensors. At the high end, the nRF54LM20A includes high-speed USB connectivity and the largest memory, providing headroom for complex applications such as Matter hubs or USB-connected peripherals.  

All four SoCs share the 128MHz Cortex-M33 processor and multi-protocol 2.4GHz radio, and come in pin-compatible QFN packages to simplify scaling. 

Security and system integration are strong features of all of the nRF54L SoCs. Each SoC includes an Arm TrustZone® trusted execution environment, along with secure boot, encrypted firmware updates and secure storage to meet IoT security requirements. A cryptographic accelerator with side-channel protection and tamper detection further safeguards sensitive data and wireless communications.  

The nRF54L SoCs also include a 128MHz RISC-V co-processor for offloading time-critical I/O tasks, enabling the system to implement software-defined peripherals and DSP functions without overloading the main CPU.
