Nordic Semiconductor Announces New Entry-Level nRF54LS05A, -B BLE Parts
New wireless systems-on-chips are expected to go into production later this year, with samples on show at Embedded World 2026 this week.
Nordic Semiconductor has announced a new pair of chips that it plans to showcase at Embedded World 2026 in Nuremberg this week, ahead of production later this year: the entry-level nRF54LS05A and -B Bluetooth Low Energy (BLE) systems-on-chips (SoCs).
"With both the nRF54LS05A and nRF54LS05B, we want to give developers an easy, confident starting point," says Nordic Semi's Øyvind Strøm of the company's latest BLE parts. "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."
The nRF54LS05A and nRF54LS05B are both built around a single Arm Cortex-M33 core running at up to 128MHz, with Nordic Semi positioning them as equally at home as the main processor in a low-power device or a communications coprocessor to a more powerful application-class chip. Both models include Bluetooth Low Energy (BLE) connectivity, and differ on in the memory on offer: the A-suffixed version has 64kB of static RAM (SRAM) on board, while the B-suffixed version ups this to 96kB for more demanding tasks; both, meanwhile, have 512kB of non-volatile storage.
The new parts are, Nordic Semi says, focused on offering the same "key features" as the existing nRF54L line-up, including ultra-low power consumption, but with a "streamlined design" that drops some of the extras in order to bring down the cost — ideal, the company claims, for applications including wireless sensors, tags, remote controls, and PC peripherals.
The company will be showcasing the new nRF54LS05A and -B at Embedded World in Nuremberg this week, at Hall 4A Booth 310; the parts are "now ready for evaluation and development," Nordic Semi says, with mass production expected to begin in the third quarter of 2026 — at an as-yet unconfirmed price point, which is expected to undercut existing parts in the nRF54L family.
