Nordic Semiconductor has introduced the nRF54LV10A, a Bluetooth LE system-on-chip designed for low-voltage, space-constrained healthcare wearables such as biosensors and continuous glucose monitors. The device operates from a 1.2 V to 1.7 V supply range and can be powered directly from a single silver-oxide coin cell, supporting compact power architectures for body-worn designs.
The nRF54LV10A adds a sub-50 nA system hibernation mode intended for shipping and storage and is offered in a 1.9 mm × 2.3 mm chip-scale package to reduce PCB area in miniature devices. It integrates a 2.4 GHz radio, a 128 MHz Arm Cortex-M33 processor, a RISC-V coprocessor, and common peripherals. Memory resources include 1 MB of non-volatile memory and 192 KB of RAM. Nordic states power consumption is 30% to 50% lower in common Bluetooth LE use cases compared with nRF52-series devices.
Security features target medical and personal data protection and include secure boot, secure firmware update, secure storage, and a Trusted Execution Environment enabled by Arm TrustZone. The SoC also includes tamper sensors intended to detect physical attack attempts and a cryptographic accelerator described as hardened against side-channel attacks.
The device also supports Bluetooth Channel Sounding alongside low-voltage operation, enabling distance measurement, indoor positioning, or presence detection features that can be used in healthcare wearables for proximity- and location-aware functions.
The nRF54LV10A is supported in the nRF Connect SDK and is available for development now. Production is expected to begin in Q2 2026, with early access programs for development kits and samples available through Nordic.
