Nordic introduces new Bluetooth LE SoCs in nRF54L series

Nordic Semiconductor has recently expanded its range of Bluetooth LE SoCs by introducing two new entry-level devices tailored for simpler, cost-focused applications. This strategic move is part of a broader effort to bring low-power connectivity to high-volume IoT designs without the need for full-featured, higher-cost SoCs. The additions are designed to cater to price-sensitive applications such as sensors and peripherals, while ensuring software and ecosystem continuity across different product tiers.

The newly unveiled nRF54LS05A and nRF54LS05B are positioned as streamlined options within the nRF54L family, offering core features like ultra-low power operation and Bluetooth LE connectivity. However, these devices come with reduced memory and peripheral configurations to optimize cost-effectiveness. They can function as standalone wireless controllers or as companion chips in multi-chip architectures, providing flexibility for developers working on modular designs or transitioning from more complex systems to simplified nodes.

These entry-level devices are well-suited for a variety of applications including sensors, asset tags, beacons, remote controls, and PC peripherals. In these scenarios, power efficiency and bill of materials (BOM) cost are often more critical than advanced processing or connectivity features. Øyvind Strøm, EVP Short-Range at Nordic Semiconductor, emphasizes the goal of providing developers with a straightforward and reliable starting point with the nRF54LS05A and nRF54LS05B.

One of the key aspects of this product launch is the seamless integration with Nordic’s existing software and development ecosystem. The devices support the same Bluetooth LE stack used across the nRF54L Series, enabling developers to leverage certifications and software components across different product lines. This approach is expected to streamline development processes, especially for companies looking to scale their product portfolios across various performance and cost levels.

Both SoCs are equipped with a 128 MHz Arm Cortex-M33 processor and Nordic’s fourth-generation Bluetooth LE radio. While the nRF54LS05A features 64 KB of RAM, the nRF54LS05B offers 96 KB, with both devices including 0.5 MB of non-volatile memory. Furthermore, the devices are pin-compatible with selected members of the nRF54L family, facilitating upgrades or product variations without the need for extensive redesigns.

By maintaining ecosystem continuity and offering cost-effective solutions for price-sensitive applications, Nordic Semiconductor’s latest entry-level Bluetooth LE SoCs are poised to address the evolving needs of IoT developers. The introduction of the nRF54LS05A and nRF54LS05B reflects a strategic approach to expanding the company’s product portfolio while ensuring compatibility and ease of integration for developers working on scalable Bluetooth designs.
