Nordic Semiconductor, a provider of low-power wireless connectivity solutions, has unveiled its new entry-level, ultra-low-power Bluetooth Low Energy (LE) Systems-on-Chip (SoCs) – the nRF54LS05A and nRF54LS05B. Both can serve as the main wireless SoC in single-chip systems, or operate as Bluetooth LE companion devices in multi-chip systems, benefiting from Nordic’s market-leading Bluetooth LE technology.

The nRF54LS05A and nRF54LS05B offer developers the key features of the nRF54L Series – robust Bluetooth LE connectivity, ultra-low-power consumption and easy-to-use software – while optimising for the development of simple, cost-efficient Bluetooth LE end-products. With Nordic’s Bluetooth LE stack serving as the industry reference, developers also benefit from proven reliability and performance. This streamlined design makes the entry-level SoCs ideal for simple applications such as sensors, tags, beacons, remotes and PC peripherals.

“With both the nRF54LS05A and nRF54LS05B, we want to give developers an easy, confident starting point,” says Øyvind Strøm, EVP Short-Range, Nordic Semiconductor. “Offering the fundamental features of our standard Bluetooth LE SoCs in combination with our software ecosystem offering ease of use, both SoCs will help level the playing field for those building lean, cost-sensitive applications”.

With these entry-level Bluetooth LE SoCs, developers can aim for their products to benefit from the same fully featured, certified Bluetooth LE stack, with full, reusable certification, used across the wider nRF54L Series. This provides robust, reliable Bluetooth LE communication with industry-leading interoperability, backed by Nordic’s long-standing role as a major contributor to the Bluetooth standard, and is trusted by thousands of developers worldwide.

The nRF54LS05A and nRF54LS05B combine a 128 MHz Arm Cortex M33 with low-leakage RAM for efficient, responsive processing in compact, ultra-low-power wireless designs. They include Nordic’s 4th-generation Bluetooth LE radio, baseline security and pin-to-pin compatibility with selected SoCs in the series for easy scalability. Support in the nRF Connect SDK Bare Metal option and a smooth migration path from the nRF52 Series help speed development and simplify transitions to the nRF54L Series’ architecture.

The nRF54LS05A and nRF54LS05B SoCs are now ready for evaluation and development. Production is expected to start in Q3 2026.
