Nordic Semiconductor nRF54L series: ultra-low power performance for next-generation wireless applications
The nRF54L series represents a leap forward in wireless microcontroller design. They deliver double the processing power and up to three times the energy efficiency of their predecessors, the nRF52, and a new ultra-low power multiprotocol radio. They are also cost-effective and at the same time offer extended battery life, faster computation, and improved wireless communication for demanding IoT and embedded applications.
nRF54L series overview
The nRF54L series comprises three highly integrated SoC variants tailored for scalable design requirements:
- nRF54L15: 1524 KB non-volatile memory (NVM), 256 KB RAM
- nRF54L10: 1012 KB NVM, 192 KB RAM
- nRF54L05: 500 KB NVM, 96 KB RAM
All versions are powered by a 128 MHz Arm Cortex-M33 processor with TrustZone security and include an advanced 2.4 GHz radio supporting Bluetooth 6.0, 802.15.4-2020 (Thread, Zigbee, Matter), and proprietary modes up to 4 Mbps. They offer ultra-low power consumption in both advertising and connected modes, significantly extending battery life in devices such as wearables, wireless sensors, and smart home systems.
Wireless performance and efficiency
In real-world testing, the nRF54L Series achieved a 35% reduction in Bluetooth LE advertising current compared to the nRF52, with typical consumption dropping from 265 µA to 173 µA. Additionally, connection-mode power draw is substantially reduced, making these chips ideal for always-on devices requiring efficient wireless connectivity.
Security and integration
The nRF54L SoCs offer advanced embedded security features including TrustZone isolation and hardware tamper detection. These devices also integrate a comprehensive range of peripherals including ADCs, timers, serial interfaces (UART, SPI, I2C), and GPIO, enabling robust edge processing in constrained environments.
Package options for flexible design
- QFN 6.0 x 6.0 mm
- WLCSP 2.4 x 2.2 mm
These nRF54L series is suitable for space-constrained applications while maintaining full-featured wireless functionality.
Evaluation and development
The nRF54L platform maintains compatibility with the existing Nordic software ecosystem, enabling faster time-to-market and simplified upgrades for teams already using nRF52-based designs. Nordic provides full development kits and tools for hands-on testing.
