Nordic Semiconductor has introduced its nRF54L Series of wireless SoCs, which includes the new nRF54L10 and nRF54L05 in addition to the previously announced nRF54L15.
Applications ranging from straightforward, high-volume goods to more complex and demanding designs are supported by the new nRF54L Series, which consists of three devices that combine a 2.4 GHz radio and MCU functionality, including CPU, memory, and peripherals, into a single ultra-low power semiconductor. Wearables, smart rings, gaming controllers, HID devices, medical equipment, smart homes, and industrial IoT goods are some of the main uses. While the nRF54L10 and nRF54L05 are designed for high-volume applications like asset trackers, smart tags, electronic shelf labels, and other cost-sensitive IoT devices, the nRF54L15 is best suited for more demanding applications.
Nordic is happy to have launched the nRF54L Series. Oyvind Strom, EVP Short-Range at Nordic Semiconductor, explains,“The launch of the nRF54L Series is a proud moment for Nordic. This new range of wireless SoCs establishes Nordic, already the world’s leading supplier of Bluetooth LE solutions, firmly at the forefront of low power wireless technology,”
Equipped for Tomorrow’s Advanced IoT Products
An Arm Cortex-M33 processor running at 128 MHz and an ultra-low-power 2.4G Hz radio are features shared by all nRF54L Series SoCs. They eliminate the need for external MCUs or extra memory by supporting wireless protocol stacks and sophisticated application software on a single device.
With 1.5 MB of non-volatile memory (NVM) and 256 KB of random-access memory (RAM), the nRF54L15 has the greatest memory capacity in the series and is perfect for demanding applications. The nRF54L05 is designed for less demanding, budget-conscious applications and has 0.5 MB NVM and 96 KB RAM, while the nRF54L10 offers a mid-range solution with 1.0 MB NVM and 192 KB RAM.
Up to 35 GPIOs and an ultra-compact 2.4 by 2.2 mm WLCSP packaging variant are available in this product line, which is 50% smaller than the similar nRF52840. A variety of pin-to-pin compatible QFN packaging for the nRF54L Series 6×6 provide design flexibility and minimise production costs.
The product series has a low-power RISC-V coprocessor in addition to its increased memory options, allowing for compact designs and addressing advanced application needs without the need for extra external components. This lowers BOM costs.
Enhanced Multiprotocol Support
With improved features such up to 4 Mbps communication rate, the nRF54L Series supports 2.4 GHz proprietary protocols, Bluetooth LE, Bluetooth Mesh, Thread, Matter, Zigbee, Amazon Sidewalk, and more. Future-proof, the series may handle Bluetooth 6.0, which includes Bluetooth Channel Sounding.
Next Generation Wireless SoCs
The industry-leading nRF52 Series is enhanced with the nRF54L Series, which doubles processing power, triples processing efficiency, and uses even less power. The new products incorporate unique intellectual property (IP) including low-leakage RAM and cutting-edge radio technologies, and they are based on Nordic’s extensive design experience. A groundbreaking shift to the 22 nm production node (TSMC’s 22ULL technology) has increased ultra-low power capabilities and processing efficiency while also greatly bolstering Nordic’s supply chain’s resilience.
Development Support and Availability
The whole nRF54L Series, including the nRF54L10 and nRF54L05, is now widely accessible for testing and development with the release of the new nRF54L15 DK (Development Kit). Together with comprehensive documentation, interactive online classes, and top-notch technical support, it includes an ecosystem of tools that facilitates development and proof of ideas rapidly.
