Nordic Semiconductor is bringing a pair of new entry-level BLE SoCs to Embedded World 2026 in Nuremberg this week, the nRF54LS05A and nRF54LS05B. These SoCs will start production later this year, with samples ready now for developers to test.
Both chips center around a single Arm Cortex-M33 core clocked at up to 128MHz, making them versatile enough to serve as the main processor in low-power devices or as a comms coprocessor alongside beefier application chips. They both pack BLE connectivity, with the main difference being RAM: 64kB SRAM on the nRF54LS05A, bumped up to 96kB on the B model for more intensive tasks. Non-volatile storage is 512kB across the board.
Nordic positions these as cost-optimized versions of their existing nRF54L series keeping the ultra-low power perks and key features but trimming extras for affordability. They’re targeting wireless sensors, tags, remote controls, and PC peripherals.
You’ll find them demoed at Nordic’s booth (Hall 4A, 310) this week. Mass production kicks off in Q3 2026, with pricing still TBA but expected to beat the current nRF54L lineup.
Leadership Comment
“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.”
